模拟施工问题（国外英文资料） Constant load calculation information: 1: one-time load calculation: mainly used for multilayer structures, and it is best to use this loading calculation method for multi-layer structures. Because the layers of the construction have a small effect on the vertical deflection of the multi-layer structure, do not use analog construction method. 2: simulate construction method 1 load: it is the normal simulation construction method load, the high-level structure, generally adopted this method computation. But for the frame shear structure, adopting this method on the basis of the guide to the internal force of shear wall under internal force particularly big, make the foundation underneath is difficult to design. And then you have the next vertical load method. 3: load simulation method 2: this is the basis of simulation method 1 general the vertical component, column, wall) increase the stiffness of 10 times for structural internal force calculation, which is then simulated loading is calculated under the condition of the construction method 1. By using this method, the force that is calculated from the base is more uniform and reasonable, which can avoid the axial force of the wall far greater than the axial force of the column. Due to the vertical component of stiffness amplification, making the level difference of vertical displacement at the ends of the beam to reduce, thus reduces the shear force, thus weakened the floor load caused by uneven stiffness and internal force redistribution, so this method is more close to the manual calculation. But I think this method artificially enlarges the line stiffness ratio of the vertical component to the horizontal component, so it is worth exploring the calculation. So, expert advice: use simulation method 1 when performing upper structure calculation; In the base calculation, the calculation result of simulated construction method 2 is used. The basic result is reasonable. (high-rise building) Reference: /b
