Jianzhu Gangjiegou Jinzhan, 2018 罕遇地震下偏心支撑框架结构需合理有效地增大消能梁段的延性和耗能能力,并减小消能梁段的损伤,以使该种结构能更好地适应当前的抗震要求。基于剪切型消能梁段的力学特性和扩孔型螺栓连接的受剪滑移能力,提出一种扩孔螺栓连接型消能梁段。采用校正的有限元方法对扩孔型螺栓连接和扩孔螺栓连接型消能梁段进行详细分析,以明确相应试件的力学性能。研究结果表明,扩孔螺栓连接型消能梁段具有高延性和强耗能等特点,能有效提高偏心支撑框架结构的抗震性能和震后功能恢复能力,并为偏心支撑框架结构的抗震设计提供新的思路和方法。

Jianzhu Gangjiegou Jinzhan, 2012 目前,空心钢管混凝土结构被大量应用和推广,但对其抗震性能的研究却比较少,制约了其在实际工程中的进一步应用。对空心普通和再生钢管混凝土柱的抗震性能进行了试验与有限元研究,首先介绍了3根空心圆钢管混凝土柱在定轴力和水平反复荷载作用下的滞回性能试验,分析了不同混凝土和空心率对试件耗能能力及位移延性等抗震性能的影响,研究表明再生混凝土构件的抗震性能要差于相应普通混凝土,而空心率越大,构件的延性和耗能能力越小。其次,采用有限元软件ABAQUS对空心钢管混凝土压弯构件的荷载-位移骨架曲线进行了大量数值计算 ...
