APPLICATION OF A NEW ELEMENT IN INTERACTIION ANALYSIS OF STRUCTURE
-
摘要: 在平面矩形单元和板单元的基础上推导了考虑法向、切向地基反力的弹性厚薄板通用单元,将它应用于上部结构、基础和地基的共同作用分析程序中,并将所得结果与常规薄板理论计算结果进行比较,验证了厚薄板通用元的正确性。Abstract: A rectangular element of thick-thin plate on elastic continuum considering both normal and tangential reactions is presented based on element of plane rectangle and plate.It can be used for superstructure-foundation-soil interaction analyses.By means of comparing this consequence with the one from thin plate-theory,the correction of the thick-thin plate-theory is concluded.
