New Standard Floor Assemble Simulation Approach for Abaqus Building Structures

The mechanical analysis of integral building structure needs the proper ABAQUS finite element analysis, but due to the ABAQUS software function limits the building structure modelling is a great workload and how to model integral structure more quickly and efficiently become a difficult problem. To reduce the workloads in ABAQUS analysis of integral structure models, the new ABAQUS standard floor assemble modelling approach and the program computational algorithm were proposed based on ABAQUS model data structure, nodes geometry transformation and horizontal surface coordinate value distinguish rule. Afterward one example engineering structure model using this standard floor assemble approach and the linear perturbation analysis were completed. The lateral displacement distribution from analysis indicated that each floor lateral displacements distributed continuously without any significant mutation and the standard floor assemble model can successfully achieve the continuous connection of the upper and the lower floors. By comparing the results of ABAQUS standard floor assemble model with that from PKPM SATWE analysis, it is proved that the ABAQUS standard floor assemble modelling is more accurate and can be applied in structure analysis.
