空心普通和再生钢管混凝土柱抗震性能研究Ⅱ:理论研究

Jianzhu Gangjiegou Jinzhan, 2012
基于前文对空心普通和再生钢管混凝土柱抗震性能的试验和有限元分析,对空心普通和再生钢管混凝土压弯构件的抗震性能进行了理论研究。首先,运用瑞利-利兹法和极限平衡理论等方法对压弯构件在单调荷载作用下的荷载-位移曲线进行了全过程分析。结合有限元参数分析结果,提出了空心普通和再生钢管混凝土压弯构件骨架曲线理论模型和位移延性系数简化计算公式,可为空心钢管混凝土结构工程实践和相关规程的修订提供理论参考。

轻钢龙骨注浆式复合墙板的抗弯性能研究

Jianzhu Gangjiegou Jinzhan, 2019
通过对2榀足尺轻钢龙骨填充玻化微珠泡沫混凝土复合墙板进行均布荷载作用下的抗弯性能试验,分析了开洞对轻钢龙骨注浆式复合墙板的荷载-挠度曲线和破坏模式的影响。利用有限元软件Abaqus建立了轻钢龙骨注浆式复合墙板的抗弯计算模型,考虑了材料本构关系模型和复杂接触模型,进行了结构非线性全过程受力分析,并将有限元分析结果与试验结果进行了验证。同时考察了影响轻钢龙骨注浆式复合墙板抗弯性能的主要参数。结果表明:开洞对轻钢龙骨注浆式复合墙板承载力有一定削弱,由于对洞口两侧的竖龙骨进行加密处理,能够有效保证开洞墙板承载力。
