摘要

利用GPU强大的并行计算能力，开发了一种结构非线性有限元静力、动力分析的高精度和高效率分析平台HSNAS(GPU)。为了验证所开发平台的计算精度和效率，分别对反复荷载作用下的钢筋混凝土构件层次和整体结构层次的拟静力试验以及典型框架结构的振动台试验进行模拟。结果表明HSNAS(GPU)平台得到的计算结果与试验结果吻合较好，该平台能较好地模拟构件轴力-弯矩-剪力的多维耦合效应以及刚度和强度退化等非线性行为，求解精度较高。与传统CPU计算平台相比，HSNAS(GPU)平台显示出12-14倍以上的加速效率。鉴于GPU的巨大计算潜能空间，所开发的计算平台为工程应用中大规模梁柱结构非线性有限元分析提供了高精度和高效率的分析手段。

Abstract

A simulation platform HSNAS(GPU) of nonlinear static and dynamic analysis based on the parallel computing ability of GPU was developed. In order to verify the precision and efficiency of the HSNAS(GPU), static cyclic loading tests and a shaking table test of reinforced concrete (RC) columns and frames were simulated using the platform HSNAS(GPU). The results of HSNAS(GPU) show a good agreement with the results of tests. Considering strength/stiffness degradation and coupling effect of axial force, shear, and bending, the complicated nonlinear behavior of RC columns could be simulated effectively and precisely. The speedups of the static and dynamic analysis using the developed platform HSNAS(GPU) achieves 12-14 times compared with traditional serial platform. Based on exploiting the potential of GPU computation, the platform HSNAS(GPU) could provide one scenario with high accuracy and efficiency for large-scale nonlinear analysis of reinforced concrete frames.
