梁悬臂施工仿真分析ansys This is the construction simulation analysis a box I recently did a cantilever model, not longer, 45+80+45, taking into account the three to start to do the prestressed reinforcement, reinforced with surface cutting body, made out of the model is too big, the No. 0 block has 100 thousand degrees of freedom, do the whole construction analysis the bridge is not, here is a simplified model of the idea is: 1: uses SOLID65 as concrete, and the LINK8 simulates the three - direction prestressing tendons 2: establishes the characteristic cross section, simplifies the box girder into several parameters, and generates the whole bridge by cycle 3: divides the characteristic section of the element, controls the mesh generation, and sweeps the finite element model of the bridge 4: considers the contact bars on the characteristic cross section and loops to produce reinforcement for each construction section The following is the command stream, please advise the teacher Fini /clear /prep7 /title, BRIDGE, DAM, SIMULATION, DEVELOPED, BY, YIFEICHONGTIAN ET, 1, SOLID65 ET, 2, LINK8 MP, PRXY, 1,0.1667 MP, DENS, 12600 MP, EX, 1,3.5E10 MP, EX, 2,1.95E11 MP, DENS, 27800 MP, PRXY, 2,0.3 Characteristics of prestressed steel bars Longitudinal reinforcement, diameter 15.24mm, standard strength 1860MPA, single tensile control tonnage 195.5kN Areagjx=1.81e-4 longitudinal, transverse, single reinforcement area Areahgjx=8.038e-4 vertical single reinforcement area *dim, gjarea, array, 3 Gjarea (1) =16*areagjx Gjarea (2) =3*areagjx Gjarea (3) =areahgjx *dim, F, array, 3 F (1) =195.5e3 F (2) =586e3 F (3) =480e3 E=1.95E11 L=0.5 *dim, delt, array, 3 Delt (1) =F (1) *L/ (E*areagjx) Delt (2) =F (2) *L/ (E*gjarea (2)) Delt (3) =F (3) *L/ (E*gjarea (3)) *dim, istrn, array, 3 Istrn (1) =delt (1) / (delt (1) +L) Istrn (2) =delt (2) / (delt (2) +L) Istrn (3) =delt (3) / (delt (3) +L) R, 2, gjarea (1), istrn (1) R, 3, gjarea (2), istrn (2) R, 4, gjarea (3), istrn (3) V_NUM=46 DUN_NUM=2 *DIM, DU
