摘要
屈曲约束支撑在实际地震时承受的荷载属于变动态荷载,实验室进行试验时均采用材料的景强度指标进行设计,文章通过Q235钢材在低周高频及超低周高频作用下的疲劳性能及破坏形式进行分析,可知加载频率的增加,Q235钢材的疲劳寿命有所提高,起破坏形式均为疲劳破坏。
Buckling-restrained brace will bear the variable dynamic load in the earthquake. Static intensity index of the material will be adopted in the laboratory examination. The paper analyzed Q235 steel fatigue performance and destructiveness under low and ultra-low frequency cyclic; and the author find that Q235 steel fatigue performance will be weaker and destruction form is fatigue rupture as frequency increased.
