屈曲约束支撑刚度与屈服力匹配关系研究

Research on matching relationship between stiffness and yield capacity of buckling restrained brace

通过研究屈曲约束支撑各参数间比例关系的取值范围,对现有钢材制作的屈曲约束支撑的刚度和屈服力匹配关系进行了研究。鉴于目前钢材市场上低屈服钢材屈服强度范围的局限性,指出目前的屈曲约束支撑提供的刚度-屈服力匹配关系并不能满足所有设计的要求的,提出应研究具有更广泛匹配关系的屈曲约束支撑,以满足设计的需要。

Matching relationship between stiffness and yield capacity of buckling restrained brace made of present steel was researched by studying the proportion relationship＇s value-choosing range of the parameters of buckling restrained brace. In view of the limitation of the yield strength range of low yield steel in current market, the paper points out that the matching relationship mentioned above can not satisfy all the design requirements, and it is necessary to develop the buckling- restrained -braces with more widely matching relationship.
