摘要:
 通过聚丙烯纤维增强异形柱中间节点核心区的试验研究,对比分析了加纤维和不加纤维的异形柱梁柱中间节点的破坏特征、承载能力和延性、滞回特性、刚度退化及耗能能力等性能指标.建立了损伤模型对节点进行累积损伤评价,并进行有限元分析.研究表明,在中间节点使用纤维增强可显著改善和提高异形柱节点的破坏形态和开裂荷载,减小节点的累积损伤,改善抗震性能,但对耗能能力影响并不显著.
Abstract:
 Based on the experiments on the core area of interior joint with specially shaped column reinforced by polypropylene fiber, such performance indexes as failure characteristic, bearing capacity and ductility, hysteresis char-acteristic, rigidity degradation, energy dissipation and cumulated damage of the joints were compared between joints with polypropylene fiber reinforcement and those without. The damage model was established to estimate the cumu-lated damage of joints and the finite element analysis was also made. Investigation shows that, when fiber is applied to the interior joint with specially shaped column, failure characteristic is improved, cracking load effectively enhanced, and cumulated damages reduced, while energy dissipation is hardly influenced.
