墩高对不对称高墩连续刚构桥力学特性的影响
Effect of Pier Height on Mechanical Properties of Asymmetric High Pier Continuous Rigid Frame Bridges
摘要
Abstract
The mechanical characteristics of asymmetric high pier continuous rigid frame bridges with dif-ferent pier heights were studied to obtain the internal force and displacement deformation characteristics of the main girders and piers of high pier continuous rigid frame bridges with different pier heights.The vertical displacement of the main girder increases with the increase of pier height,with an average in-crease of 14.3％at the maximum displacement,and the shear force of the main girder at the top of the pier decreases with the increase of pier height,with an average change of rate of 37.1％.关键词
