【摘要】 MPC法是处理实体单元与梁、壳单元连接问题的一种常用方法,为探明其在水电站厂房这类复杂结构建模中的适用性,在建模时首先采用MPC法对实体单元与梁、壳单元进行连接,然后分别用于静力和动力分析中,并与全部采用实体单元建模的计算结果进行了比较分析。研究结果表明,MPC法能够有效实现三维实体单元与梁、壳单元的正确连接,适合在水电站厂房结构建模中推广应用。更多还原

【Abstract】 The MPC method is a common approach to the problem of uncoordinated connection between solid elements and beams or shell elements. In order to investigate its applicability in analyzing complex structures such as hydropower plants,a hydropower house model was built by using the MPC method. Then the static and dynamic characteristics of the hydropower house were calculated for further study. In order to demonstrate the correctness of this analysis,a model simulated only by solid elements was built for comparison. The results indicate that the MPC method can effectively achieve the proper connection between the beam,shell and solid elements. And it is worthy of application in hydropower plant modeling.更多还原
