考虑P-△效应的钢筋混凝土空心高墩地震响应分析
Seismic Response Analysis of High Hollow RC Piers Considering Effect P - Δ
摘要
Abstract
Considering the two influence of internal force and deformation conditions, the finite element software ANSYS is used to simulate the seismic response for 78 m reinforced concrete hollow high pier. According to the Newmark - βTime History Analysis, the first two modal maps of piers were done under the Tianjin Seismis which was input into the high - piers. And according to the Newmark successive incremental method, the two modal maps were done under the coupling which includes p - A effects and seismic response. In the graph, seismis response value increases when p - A effects were considered. With the increase in height of the piers, the moment valve of pier buttom increases more and more. When the height of pier approaches 80 meters, it tends to line up.关键词
