Application of CPU+GPU parallel computing technology in nonlinear analysis of complex structuresQiao Baojuan1，2, Li Zhishan1, Cao Shengtao1，2, Liu Chunming1,2, Hou Xiaowu1，2, Yang Zhiyong1,2(1 Guangzhou CABR&SC Co., Ltd., Guangzhou 510170, China; 2 CABR Technology Co., Ltd., Beijing 100013, China)Abstract: The CPU+ GPU parallel computing technology adopted by PKPM-SAUSAGE software was discussed. The implementation details of parallel computing were introduced combined with the steel and concrete constitutive models, fiber beam and layered shell elements, Rayleigh damping and modal damping models, and the explicit integration analysis method. The efficiency of parallel computing was tested as well. The test shows that the application of CPU+GPU parallel computing technology greatly improves the computing efficiency of nonlinear analysis of complex structures. A practical reinforced concrete frame-corewall structure was taken as an example to carry out dynamic elastic-plastic time-history analysis under the rare earthquake by PKPM-SAUSAGE software and ABAQUS software. The results verify the correctness and high-efficiency of CPU+GPU parallel computing technology of PKPM-SAUSAGE software.Keywords:CPU+GPU parallel computing technology; elastic-plastic time-history analysis; PKPM-SAUSAGE software; ABAQUS software作者簡介：喬保娟，碩士，工程師，Email：qiaobaojuan@cabrtech.com。
