In recent years, non-welded building hardware that can be installed by bolt assembly is used. However, there is a need for a method to compensate for the occurrence of buckling at the bolted portion at the time of construction. The purpose of this study is to evaluate the behavior of joints between steel square pipe and fastener.

The non-welded building hardware method can reduce accidents caused by welding, and can be constructed by bolt assembly, which can reduce labor costs and shorten the construction period. The purpose of this study is to evaluate the behavior of joints of non-welded and welded of building hardware frame

The non-welded building hardware method can reduce accidents caused by welding, and can be constructed by bolt assembly, which can reduce labor costs and shorten the construction period. This study is to compare and verify the performance according to the location where the brackets are joined to the joints using the non-welded building hardware method

In recent years, non-welded building hardware that can be installed by bolt assembly is used, which does not require fire prevention related materials, fire fighting equipment and personnel. However, there is a need for a method to compensate for the occurrence of buckling at the bolted portion at the time of construction.The purpose of this study is to evaluate the behavior of joints that can control the sliding between members by using anti slip brackets.

When attaching the building exterior, builder used welded-building hardware in general. But it caused variety accidents like fires and explosions. Thus in this study, we developed the building hardware that not use welding and can follow the structures horizontal displacement when an earthquake occurs in the load building. And shaking table test was conducted.
