在平面坐标中建立某个平面内的主框架的sketch,然后生成一个part,然后就可在3D空间中构建你想要得框架的。 用写input的方式可以很快的建立这个模型。 input文件的格式和大多数有限元程序差不多比如: *HEADING AN ANALYSIS FOR 8STORY FRAME STRUCTURE . **CREATE THE NODES *NODE 1, 0.0000, 0.0000 17, 18.0000, 0.0000 **CREATE NODES *NGEN, NSET=S0 1, 17, 1 *NSET, NSET=Base 1, 17 *NSET, NSET=Middle 9 *ELEMENT, TYPE=B23 1, 1, 2 *ELGEN, ELSET=level0 1, 16, 1, 1, *BEAM SECTION, ELSET=B8, MATERIAL=steel, SECTION=I 0.375, 0.75, 0.40, 0.40, 0.036, 0.036, 0.019 0.,0.,-1. **DEFINE MATERIAL *MATERIAL, NAME=steel *ELASTIC 2.058E+11, 0.2963 *PLASTIC, HARDENING=KINEMATIC 258720000.0, 0.0 464520000.0, 0.049 **DEFINE BOUNDARY CONDITION *BOUNDARY Base, 1, 2 Base, 6, 6 **---------------------------------------------------- *STEP, NAME=gravity *STATIC 0.1, 1.0, 1.0E-5, 1.0 *CLOAD S0, 2, -60000.0 *END STEP **---------------------------------------------------- *STEP, NAME=staticstepupper, INC=999 *STATIC 1.0, 1.0, 1.0E-5, 1.0 *BOUNDARY Middle, 2, 2, 0.05 *RESTART, WRITE, OVERLAY *FILE FORMAT, ASCII *NODE FILE, NSET=Base, FREQUENCY=999 RF *END STEP ============================== | |
