Abstract

In order to realize the buckling-restrained brace (BRB) with high energy absorption performance, it is important to prevent premature local bulging failure of the restraining part. In this study, the strength of BRB to resist local bulging failure of the restraining part is considered to be the minimum value of the strength of the steel plate considering the influence of the effect of filling materials and the strength to resist bearing failure of the filling materials. Local bulging failure is prevented by the value to resist local bulging failure larger than the force acting in the out-of-plane direction.

钢砂浆板抗屈曲支撑试验研究

为了实现具有高能量吸收性能的屈曲约束支撑，防止约束部件过早局部胀形失效是十分重要的。在本研究中，考虑填充材料的影响和填充材料的抗承载破坏强度，BRB抗约束部分局部胀形破坏的强度被认为是钢板强度的最小值。当抗局部胀形破坏的值大于作用于面外方向的力时，可以防止局部胀形破坏。

期刊介绍： The Architectural Institute of Japan’s Journal of Structural and Construction Engineering aim to pursue theories for building and maintaining pieces of architecture as well as the cities or areas surrounding them, and to accumulate and systematize the knowledge needed to put those theories into practice. The Journal of Structural and Construction Engineering focuses on research results in the specific fields of “building materials and construction” and “structures.” Accordingly, it compiles articles in the following areas, disseminates relevant information, and hosts discussions: ・Concrete, steel, and inorganic materials ・Timber and organic materials ・Finishing materials ・Construction and quality management ・Applied mechanics ・Loads and reliability on structures ・Building foundations ・Timber structures ・Steel structures ・Reinforced concrete structures ・Shell and spatial structures ・Engineering seismology and structural dynamics ・Other composite structures
