Construction projects and buildings are becoming taller and larger, and the size of water tanks of production facilities and high-rise buildings is also gradually increasing. Most large water tanks apply a waterproofing layer to the water tank type concrete structure. The application of polyurea coating materials, which are excellent in water resistance, chemical resistance, physical performance, rapid hardening, and workability is gradually increasing as waterproofing and anticorrosion layer for water tank. As a result, defects such as water leakage and damage to the waterproofing layer are continuously occurring, causing production disruption, setback to users. Therefore, it is required to review suitability through performance verification of the waterproofing and anticorrosion system.

The seamless integration of the architecture and structure of a tall building plays a key role in establishing a recognizable and iconic design. The structural system developed for Shenzhen Rural Commercial Bank Headquarters (SRCBH) utilizes enhanced structural innovations unique to the tower's geometry to improve structural and sustainability performance. SRCBH utilizes a steel diagrid system pulled outside of the enclosure line with diaphragm forces resolved primarily by corner diagonal beams. During the design process the structural systems underwent performance based design and optimization for wind and seismic loading. Resiliency was prioritized for structural design as well as fire resistance. More closely integrating the structure of a building with its architecture and sustainability goals can lead to unique and innovative towers with a timeless expression.

This paper focuses on how the coupling of the columns and walls through the structural slab contributes to the overall stiffness and strength of lateral systems. The rationale and procedures behind the design approach, which may offer a shift from more conventional assumptions made regarding compatibility and connectivity of gravity and lateral structural systems, will be introduced. The impacts on serviceability and strength design will be discussed, and observations on key design and analysis approaches will be featured. Mass and stiffness assumptions will also be reviewed. A case study on the topic will be presented describing implementation of slab coupling into engineering of a building project.

With the rise in CPU power and the generalization and popularity of computers, engineering practice also changed from hand calculations to 3D computer models, from elastic linear analysis to 3D nonlinear static analysis and 3D nonlinear transient dynamic analysis. Thanks to holistic design approach and current trends in freeform and contemporary architecture, BIM concept is no longer a dream but also a reality. BIM is not just providing a media for better co-ordination but also to shorten the round-the-clock time in updating models to match with other professional disciplines. With the parametric modeling tools, structural information is also linked with BIM system and quickly produces analysis and design results from checking to fabrication. This paper presents a new framework which not just linked the BIM system by means of parametric mean but also create and produce connection FE model and fabrication drawings etc. This framework will facilitate structural engineers to produce well co-ordinate, optimized and safe structures.

As recent construction projects aim to build higher and bigger buildings, lifting operation is getting increasingly important in construction sites. Accordingly, as tower cranes get higher and higher, disasters involving tower cranes are also on the rise. According to occupational incident statistics of the Korea Occupational Health & Safety Agency (KOHSA), most of such incidents occur in installation, dismantling and climbing phases of tower crane. Therefore, it is essential to develop preventative measures to secure safety of tower crane operations, with critical focus on installation, dismantling and climbing of tower crane. Hence, this research attempts to measure criticality of key risk factors in installation, dismantling and climbing phases of tower crane on construction site and propose necessary safety measures. As a result, conclusions herein will contribute to minimize disasters and incidents involving tower cranes in high-rise building construction sites.

In this paper, the applicability of PHC piles to replace Myanmar local piles were evaluated. In Myanmar, based on the size of the building, foundation design and field applications are carried out using bored pile and square pile. As a result of the analysis, the application of PHC pile is more economical than conventional bored pile or square pile which was applied in the high rise (17-story) and middle story (12-story) buildings. However, in the low - rise (8-story) building, the application of the existing square piles was found to be more economical than PHC pile.

The volume of material and number of workers mobilized has been on the rise in line with the domestic projects getting higher, larger and complex currently. Particularly for the project in downtown, delivering the resources in timely manner is very crucial in carrying out the overall project as scheduled. Inappropriate lifting plan often causes inefficiency over the entire project, resulting in increase in schedule and cost. Despite of such importance of lifting plan for architectural work, lifting plans at the most of domestic projects, except a few cases for large scale high-rise buildings, have been heavily dependent on engineer's personal experience and intuition alone. To deal with such problems, the study was intended to develop and suggest a systematic and objective process for determining the lift, categorizing the lifting equipment into the two types, one for workers and another for material.

Korea's housing polices, which have tended to be focused on quantity rather than quality, have since the 1970s given rise to a housing culture centered on apartment units. Such housing polices have resulted in urban sprawl in the metropolitan areas, and a growing polarization between urban and rural areas. In addition, the issue of "dehumanization" has emerged as a result of the interchangeable urban landscapes and the growing number of high-rise residential buildings. In short, the residential communities of the past, such as towns and villages, have disappeared and been replaced with societies that value individuality and anonymity. The purpose of this paper is to analyze urban structure Gyeongju traditional housing complex. This is to analyze the traditional Hanok residential complex of superiority and characteristics of Gyeongju. This enables future planning should be introduced in Gyeongju hanok.

The construction of economic, efficient and stable process has been a major challenge as the building are getting high-rise and biger. Low-rise buildings widely have been used Euro-form in the past. Recently, we are mainly using Al-form which can respond to chang in the various structures. we should be used in combination with Al-form and Gang-form to ensure the quality and construction process, according to the change of various elevations. Recently construction project is reguired diversification of elevation. And we apply the open balcony on the general architecture as well as public housing. Accordingly, Al-form & Gang-form has been applied the change of elevation, We further apply design and construction as proposal of issues and alternatives.

The unit curtain wall is an exterior finish currently used on the exterior walls of high-rise buildings. Curtain walls used as non-endurance walls are largely classified into stick curtain walls and unit curtain walls, and their use has recently been on the rise to reduce risks at construction sites through factory manufacturing. Accordingly, this study attempted to examine the insulation performance according to the shape of the unit curtain wall profile through insulation simulation.
