A textile and capillary tube composite panel(TCP) was developed to simultaneously retrofit the seismic performance and the energy efficiency (e.g. heating or insulation performance) of existing unreinforced masonry (URM) buildings. TCP is a light-weight mortar panel in which carbon textile reinforcements and capillary tubes are embedded. Textile reinforcements plays a role of seismic retrofit and capillary tubes that hot water circulates contribute to the energy retrofit. In this paper, the static cyclic loading tests were performed on the masonry walls with/without TCP to understand the seismic retrofit effect of TCP retrofit and the results were summarized. The results of the test showed that the TCP contributed to increase the capacity of the Shear strength and ductility of the URM walls. In addition, the deformation of the wall after cracking was substantially controlled by the carbon textile.

This study investigates the shear behavior of architectural masonry veneer wall reinforced with specific reinforcement details proposed by this study. For this purpose, experimental tests were conducted using one un-reinforced masonry(URM) wall specimen and three reinforced masonry(RM) wall specimens under quasi static cyclic loads. Un-reinforced(plain) masonry wall is expressed that behavior and failure mode are different for aspect ratio(L/H) and axial compressive force. The test variables are wall aspect ratio and presence of reinforcement. These specimens are masonry structure for architectural clading that is not to exist the axial compressive force. thus the axial compressive force is excepted from test variable. Test result, Behavior of specimens are dominated over rocking mode, but final failure modes are combined with different behaviors. And FEMA273 has proposed the equation of shear strength of masonry pier subjected to in-plane loading. Shear strength equations are classified four types of failure mode that is Rocking, and Toe-Crushing, Bed-Joint-Sliding and Diagonal-Tension. FEMA273 equations predict the behavior modes well, but shear strength is shown in different result.

Construction project involves numerous repetitive operations. Especially in high-rise and apartment houses projects, the amount of repetitive operations increase and a preceding operations delay causes serious damage to the total duration of the project. This study deducts work delay factors by site engineer interview and survey. The study analyzes daily report data to deduct crucial processes affecting masonry work which has been investigated to be one of preliminary processes conducted at the beginning of finish work.

We intend to offer theoretical bases of earth construction technology through the analysis of cases of brickworks and plastering works in the city of Gumi, Kyeongsangbukdo. We search for those instances of earth buildings to confirm the trend that earth construction is recognized as environment-friendly, sustainable and newly spotlighted field to alternatives of building construction. We made a frame of analysis through theoretical consideration about earth construction and prior study. Then, we analyzed the selected buildings which is selected by priority in the city of Gumi as authorized preservation value, cultural assets and recently built modern constructions. We found out some problems in structural strength, durability and fire proofing and the invisible development of technologies of earth construction method in this case analysis.

In Korea, there still exist a number of modern architectural structures which were built from 1876 - when Korea first opened its port to foreign trade - to the early 1960s. Modern architectures have been rather neglected from the study of Korean architecture history partly because of its short period and negative attitude toward them that they are remains of the Japanese colonial period. However, interest in modern structures is recently increasing, and researches and studies are actively going on. This dissertation is a study on brick laying techniques and design characteristics of Modern brick structure churches in Jeonbuk-province. The results demonstrate that modern brick structure churches in Jeonbuk-province have become small and simple with time and that their structures and designs are closely related.

Appropriate management of the finish works in construction project is one of most important activities that must be conducted considering the total duration of the project. Masonry work is a fundamental process that is performed in the preliminary steps of finish works. However, it has been investigated that the analysis of delay factors affecting masonry work has been neglected in the domestic construction site. Therefore, this study deducts delay factors affecting masonry work by literature review and survey on site engineers and labors. This study has been conducted as a preliminary step of developing a construction project interference management system which is expected to suggest objective information for the decision making in construction sites.
