求翻译：网架结构由于负荷加固，施工的先后顺序和焊接收缩变形对结构施工过程中和施工完毕后结构的变形、构件内力有较大影响。因此，结合实际施工条件并采用ANSYS有限元软件对不同施工过程进行模拟分析。根据分析结果，确定合理的加固施工方案以及整个结构在焊接残余应力的作用下产生起拱，为工程设计和施工提供科学参考是什么意思？

As the load reinforcement grid structure, sequence of construction and welding shrinkage of the structure of the construction process and construction of the structure after the deformation, internal force components have a greater impact. Therefore, with the actual construction conditions and the u

Network Load reinforced, and the structure because the sequencing and construction welding shrink deformation during the course of building and construction of structures after power structure within the deformation, components have a much greater impact. Therefore, actual construction conditions AN

The wire table structure as a result of the load reinforcement, the construction successively the smooth and the welding shrinkage strain finished the structure distortion, the component endogenic force after the structure construction process neutral construction has affects greatly.Therefore, the

Grid structure reinforcement due to load, order of construction and welding shrinkage deformation of structures in construction process and construction after the deformation of the structure, components of internal force has a greater impact. Therefore, the actual construction conditions and the us
