Seismic Forces

In recent years in Taiwan, some pedestrians were injured by falling external wall tiles. Exterior wall tile fell down for the temperature or other effects of seismic forces, becoming a potential public safety crisis. Office of Building Administration of Taoyuan City Government started inspecting high-rise buildings, which were over eleven stories and constructed before 1995 in Taoyuan city from 2015 to 2016. This study is a contract research. We inspected 298 high-rise buildings’ external wall tiles in Taoyuan City for city government. In this study, we classified the risk of buildings from Level A to E. D and E, which were regarded as the dangerous buildings and in need of repair immediately. D and E accounted for 41.6% percent of total buildings. We also concluded the data in the viewpoints of building age, story, exterior material, direction, and district. The authors hope the conclusion of this study could be submitted as reference material of inspection system, as well as give a significant suggestion to the periodic inspection approach in the future.

Wall Construction

Tile is one of the most popular materials for high-rise building exterior wall construction in Taiwan. High-rise buildings in Taiwan were first built approximately 35 years ago. Wall tiles of these buildings currently are deteriorated facing the need of repair. In recent years, subject of exterior wall tile inspection at high-rise building have gained considerable attention. Taiwan government enacted the regulations on fire evacuation and equipment inspection for building safety. And attempt to add the article of exterior wall inspection for building safety. In other ways, high-rise buildings were first built approximately 50 years ago in Japan. Inspection and repair work for high-rise buildings plays an important role in the building construction market in Japan. Jurisdiction of Ministry of Land, Infrastructure, Transport and Tourism legislate the regulations “Periodic Report System”. Exterior wall inspection methods were regulated under these regulations. In order to sustain safety quality environment within existent high-rise buildings, it is necessary for Taiwan government to legislate on exterior wall inspection today. The purpose of this study is to compare the regulations for inspection method of high-rise building exterior wall tile in Taiwan and Japan. We hope the conclusion of this study could give a significant suggestion to Taiwan building inspection method in the future.

Fire overflow on exterior wall with thermal insulation system has been studied by numerical simulation. The spread laws of fire overflow are analyzed through the temperature distribution near the window. The computational results are compared with those of test in the Exterior Insulation Fire Barrier Technical Guidelines (EIFBTG). It has been found that the calculated maximum temperature points is closed to the test on the first floor, the first ceiling, and the points near the above two windows. However, there are differences between two kinds of results above two floors and ceilings, and the points near the first window. It has also shown that when the HHR is 7.5KW, the scope of damage of exterior thermal insulation layer is about 15 square meters near the window. The research would provide reference for fire protection design of exterior wall thermal insulation in the high-rise buildings.

Passive Fire Protection

The fire in high-rise buildings is perhaps more dangerous than those occur in normal buildings because of the strong stack effect and wind effect on the fire. The wind effects on the wind flame spread across the exterior wall of the high rise building are studied in this paper by the numerical methods. The results show that high wind speed will change the wind flame spread direction and make the room inclined above the fire room more danger, especially the room at the same floor adjacent to the fire room. Special passive fire protection measures should be taken under these kinds of conditions.

External thermal insulation system of Cast-in-situ concrete exterior wall in high-rise civil building includes with network and without network system, wherein the cast-in-place concrete exterior wall insulation without network system is the most economical and the external thermal insulation system. This system applies to new buildings, can also be applied to energy saving renovation of existing buildings. In this paper, the system technology without steelmesh is synthetically introduced so that more engineers can know and use it better.
