1、箱型梁加固分析以及存在问题和将来计划尺寸安排桥梁尺寸30.6+2*36+30.6=133.3m截面尺寸梁宽8.65m桥面尺寸0.5+3.75*2+1.3+3.75*2+0.5两根梁，四车道Ansys建模思路1、定义一个solid45和一个shell632定义shell实常数0.05,0.10,0.15分别用于加固时使用定义材料属性：两个Material建立截面拉伸建立梁CopyandGlue对结构进行hex-mapped划分网格加约束、加重力以及荷载Solve后处理Ansys建模截面逐个拉伸截面第一根梁建模完成Copy+GLUE网格划分加载、汽15满载计算时出错经百度知道可能是网格划分或者

2、约束不够等原因。用小题做模拟y方向位移加固前后对比加固前后y向总应变YZ面的剪应变计划与疑问1、解决建模时出现的问题2、加固计划分别在梁底板、顶板、侧面进行0.05m、0.10m、0.15m钢板粘贴，在一根梁上数据模拟成功。进行后期手算及计算书及图形绘制计划在六月一日前完成设计内容。以下是我ansys操作时部分命令流省略了部分体拉伸过程命令/COM,Structural!*/PREP7!*ET,1,SOLID45!*ET,2,SHELL63!*R,1,0.05,,,,,,RMORE,,,,RMORERMORE,,!*R,2,0.10,,,,,,RMORE,,,,RMORERMORE,,!
