摘要
本文首先对P-δ效应,P-Δ效应与二阶效应从定义上加以区分,并以悬臂柱为例说明,然后以框架柱为例,分别推出了反映二者影响的单元刚度矩阵.
P-δeffects, P-△effects and second order effects have been distinguished in the definition at first, cantilever columns set as examples to explain the difference. Then frame columns are taken as examples to conclude respective element stiffness matrixe influenced by these two effects.
