| 摘 要： | 为了验证设置碎石垫层的地基对上部建筑物的减振性能,用ANSYS10.0软件里的ANSYS/LS-DYNA显式积分程序对两种平面框架——地基设置碎石垫层的平面框架和地基未设置碎石垫层的平面框架进行地震响应模拟分析.在程序模拟中,将碎石垫层的厚度取为1 000 mm.由于整个碎石层相对厚度很小则其每一薄层动剪切模量取等值.模拟试验结果表明,在水平地震波的作用下,地基设置碎石垫层的平面框架的最大正位移较地基未设置碎石垫层的平面框架减少了56.08%,最大负位移减少了56.72%.因此,设置碎石垫层的地基在一定程度上有助于提高上部建筑物的抗震能力.

| Abstract: | In order to verify the damping effects of the foundation with gravel layers on the upper building,ANSYS/LS-DYNA ecplicit integration procedures in the ANSYS 10.0 software available for two kinds of plane frames(one with foundation set with stone cushion and the other without stone cushion) were adopted to conduct seismic response simulation analysis.The thickness of the gravel cushion were taken as 1000 mm in the simulation process.The equivalent dynamic shear modulus was choosen,for the relative thickness ... |
