Purpose - The purpose of this study was to expound the packaging framework system(PFS) under international trade rules. Design/methodology/approach - This study analyzed packaging framework system and packaging regulations and technical standards in international regulations and major countries and classified these in some standards Findings - First, the study provides packaging provisions associated with packaging regulations and technical standards (PRTS). Then, the basis of PFS in international trade rules was proposed; it is believed that the PFS was composed of packaging legal system in WTO institutional framework (WTO-PLS), international organization packaging standard system (IO-PSS) and major countries or regions packaging regulatory system (MCR-PRS). Secondly, this paper expounded relations and legal characteristics of the three packaging systems. Finally, This study investigated PRTS coverage under technical barriers to trade (TBT) and Sanitary and Phytosanitary measures (SPS). Research implications or Originality - The regulations associated with PRTS have played a key role in challenges to merchandise trade in international trade. This study has significance in classifying packaging related reticulations into several criteria unlike previous studies. Therefore it is hope that this study can provide a supplementary document for the existing research of PRTS.

Purpose - We assess the trade remedies rules in a host of Korea's FTAs to explore the trade policies for the effective implementation of FTA trade remedies rules. Also we develop the strategies of the future FTA negotiations of trade remedies rules. Design/methodology - After we review the key features of FTA trade remedies rules, we examine whether the rules are WTO-consistent or not. Next, we touch upon the WTO-plus characteristics of some provisions. Our main methodology is to compare the trade remedies rules in the numerous Korea's FTAs. Another methodology is to link those rules to the relevant WTO agreements and WTO dispute cases with a view to drawing lessons for trade policies and FTA negotiations. Findings - We find that most of the trade remedies rules are WTO-consistent. Moreover, we find that notification and consultation requirment, mandatory lesser duty rule, explicit prohibition of zeroing method, and public interest clause are WTO-plus. We also find that there are limitiations in the application of some global safeguard exclusion rules because of their non-mandatory nature. Originality/value - While most of previous studies focus mainly on the unique aspects of specific FTAs, our study analyzes comprehensively the trade remedies rules in the various Korea's FTAs. Based on the comprehensive analysis, we figure out the areas to be clarified and improved for the effective implementation of FTAs and the strategies for the future FTA trade remedies negotiations. As a consequence, our paper is expected to contribute to the academic research on FTA policies as well as the national economy.

The retrofit of existing structures in high seismic zones is a crucial issue in the earthquake engineering field. The interest of the research community is particularly high for the structures that do not respect current seismic codes and present structural deficiencies such as poor detailing and lack of capacity design provisions. A reinforced concrete (RC) school building is used as case study to show the influence of different knowledge levels on the seismic retrofitting cost assessment. The safety assessment of the case study building highlights deficiencies under both vertical and seismic loads. By considering all the possible knowledge levels defined by the Italian such as by the European codes in order to derive the mechanical properties of the school building constitutive materials, the retrofit operations are designed to achieve different seismic safety thresholds. The retrofit structural costs are calculated and summed up to the costs for in-situ in tests. The paper shows how for the case study building the major costs spent for a large number of in-situ tests allows to save a consistent amount of money for retrofit operations. The hypothesis of demolition and reconstruction of the building is also compared in terms of costs with all the analyzed retrofit options.

Purpose - This paper aims at analyzing the functions and effectiveness of the cooperation agenda in Free Trade Agreements (FTAs), focusing on the cases of Asian countries. This paper estimates the contribution of this agenda to the sustainable development in Asia by providing the 'side payment' of the economic integration that encourages foreign investment and change in global value chains (GVC). Design/methodology - This study analyzes the functions of the cooperation chapter in FTAs by applying the cooperative game theory and reviewing the structures of the related FTAs. Also, as an empirical study, the existing FTA provisions and related development assistant programs in Asia are reviewed in this paper, especially focusing on the FTAs signed by Korea. Findings - Our main findings can be summarized as follows: The drawback of the economic integration, which would be the imbalanced economic benefit, can be redressed by the cooperation chapter in FTAs functioning as a 'side payment'. Indeed, as the examples of Korean FTAs show, more foreign investment and the GVC expansion in Asian countries have been encouraged thanks to the implementation of the cooperation chapters. Originality/value - This paper attempts to find how a legally binding agreement would influence the cooperation agenda in Asia which has never been analyzed despite the increasing number of so-called 'cooperation' chapters in the FTAs.

Bridge fire hazard has become a growing concern over the last decade due to the rapid increase of ground transportation of hazardous materials and resulting fire incidents. The lack of fire safety provisions in steel bridges can be a significant issue owing steel thermal properties that lead to fast degradation of steel properties at elevated temperatures. Alternatively, the development of composite action between steel girders and concrete decks can increase the fire resistance of steel bridges and meet fire safety requirements in some applications. This paper reviews the fire problem in steel bridges and the fire behavior of composite steel-concrete bridge girders. A numerical model is developed to trace the fire response of a typical bridge girder and is validated using measurements from fire tests. The selected bridge girder is composed by a hot rolled steel section strengthened with bearing stiffeners at midspan and supports. A concrete slab sitting on the top of the girder is connected to the slab through shear studs to provide full composite action. The validated numerical model was used to investigate the fire resistance of real scale bridge girders and the effect of the composite action under different scenarios (standard and hydrocarbon fires). Results showed that composite action can significantly increase the fire resistance of steel bridge girders. Besides, fire severity played an important role in the fire behavior of composite girders and both factors should be taken into consideration in the design of steel bridges for fire safety.

Shear lag phenomenon has long been considered in numerous structural codes; however, the AISC provisions have now no longer proposed any unique equation to calculate the shear lag ratio in bolted connections for angles in general. It is noticeable that, however, codes used in this case are largely conservative and need to be amended. A parametric study consisting of 27 angle sections with equal legs and different with bolted connections was performed to investigate the effects of shear lag on the ultimate tensile capacity of angle members. The main parameters were: steel grade, connection length and eccentricity from the center of the plate, as well as the number of rows of bolts parallel to the applied force. The test results were compared with the predictions of the classical 1-x/l law proposed by Mons and Chesen to investigate its application to quantify the effect of shear lag. A parametric study was performed using valid FE models that cover a wide range of parameters. Finally, based on the numerical results, design considerations were proposed to quantify the effect of shear lag on the ultimate tensile capacity of the tensile members.

Structural vibration induced by earthquake hazards is one of the most significant concerns in structure performance-based design. Structural hazards evoked from seismic events must be properly identified to make buildings resilient enough to withstand extreme earthquake loadings. To investigate the effects of combined earthquake-resistant systems, shear walls and five types of dampers are incorporated in nineteen structural models by altering their arrangements. All the building models were developed as per ACI 318-14 and ASCE 7-16. Seismic fragility curves were developed from the incremental dynamic analyses (IDA) performed by using seven sets of ground motions, and eventually, by following FEMA P695 provisions, the collapse margin ratio (CMR) was computed from the collapse curves. It is evident from the results that the seismic performance of the proposed combined shear wall-damper system is significantly better than the models equipped with shear walls only. The scrutinized dual seismic resisting system is expected to be applied practically to ensure a multi-level shield for tall structures in high seismic risk zones.

Seismic design codes permit the use of Equivalent Static Analysis of buildings considering torsional eccentricity e with dynamic amplification factors on structural eccentricity and some accidental eccentricity. Estimation of e in buildings is not addressed in codes. This paper presents a simple approximate method to estimate e in RC Moment Frame and RC Structural Wall buildings, which required no detailed structural analysis. The method is validated by 3D analysis (using commercial structural analysis software) of a spectrum of building. Results show that dynamic amplification factor should be applied on torsional eccentricity when performing Response Spectrum Analysis also. Also, irregular or mixed modes of oscillation arise in torsionally unsymmetrical buildings owing to poor geometric distribution of mass and stiffness in plan, which is captured by the mass participation ratio. These irregular modes can be avoided in buildings of any plan geometry by limiting the two critical parameters (normalised torsional eccentricity e/B and Natural Period Ratio 𝜏 =T_𝜃/T, where B is building lateral dimension, T_𝜃 uncoupled torsional natural period and T uncoupled translational natural period). Suggestions are made for new building code provisions.

Purpose - Disputes arising from documentary letter of credit transactions are not decreasing. According to a statistical data from the ICC, 60-70% of letters of credit in use around the world, so, Incoterms rule specifically defines the bill of lading review procedure. Research design, data, and methodology - The refusal due to large or small inconsistencies in terms and conditions when first presenting documents with bill of lading. First of all, confusion was caused by the ambiguous regulation as the bill of lading is a document that serves as evidence of the transportation contract. Result - Bill of lading indicates the rights to the cargo as well as a bill of lading, which is evidence of a transportation contract concluded between carriers, is a document that allows a carrier to receive or ship cargo and ship it by sea. It is a security that promises to be delivered through transportation to the rightful holder of the bill of lading. Conclusion - Because of its importance, the Uniform customs practices for Letters of Credit stipulate acceptance requirements for transport documents, including bills of lading. In addition, the International Standard Banking Practices (ISBP) established by the International Chamber of Commerce also provide supplementary provisions.

This study investigates reliability based design criteria for the spiral R.C. columns, and proposes practical algorithm which is based on Ellingwood's algorithm for the reliability analysis and the derivation of reliability based design criteria. Cornell's MFOSM theory is used for the derivation of the algorithm for the evaluation of uncertainties associated with resistances, whereas the magnitude of the uncertainties associated with load effects are chosen primarily by considering our level of practice. And thus the uncertainties so obtained are applied for the relilability analysis and the derivation of reliability based design criteria. A target reliability (${\beta}_0=3.5$) is selected as an appropriate value by comparing the values used in foreign countries and by analyzing, the reliability levels of our current USD and WSD design standards. Then, a set of load and resistance factors corresponding to the target reliability is proposed as a reliability based design provision, and furthermore a set of allowable stresses for reinforcing steel and concrete having same level of reliability with the corresponding LRFD criteria is also propared for the current WSD design provision. It may be concluded that the proposed LRFD reliability based design provisions and the corresponding allowable stresses give more rational design than the current code for spiral R.C. columns.
