Development and application of SAPTIS——a software of multi-field simulation and nonlinear analysis of complex structures (Part Ⅰ)
摘要
Abstract
SAPTIS (Structure Analysis Program for Temperature and Induced Stress) —a software of multi-field simulation and nonlinear analysis of complex structures is introduced herein, which includes element type, equation solver, whole process simulation on excavation and concrete pouring for dam construction, hydration heat model, water cooling model, temperature boundary condition, elastic modulus model, creep model, autogenous volume deformation, and property of MgO concrete, etc. , and then the fruitful expression methods of analysis results are given as well. Up to now, this software has been successfully applied to the simulations on temperature and stress fields and studies on temperature control, crack prevention and real operation behavior of dam for over 40 large and medium sized concrete dams and the other relevant structures of water resources and hydropower projects such as Sanxia, Ertan, Longtan, Xiaowan, Xiluodu, Jinping, Danjiangkou, etc. ; from which better e-conomic benefits have been obtained. The application results show that the thermal property of concrete materials and the stress-strain property of concrete structures can be accurately reflected with the models applied by SAPTIS with the merits of quick calculation speed, large-scale computing ability, high precision results, etc.关键词
