某核岛厂房基于MPC方法的设备荷载模拟分析

Simulation analysis of equipment load by MPC method in a nuclear island plant

介绍了核电厂房目前设备荷载的两种通用施加方法,对多点约束加载(MPC)施加竖向设备荷载进行了误差分析。针对某核电厂房内某楼板两个实际设备荷载的布置情况,通过设备荷载水平力、弯矩对楼板配筋的增大影响和配筋裕量的比较,验证配筋可靠性和MPC方法施加设备荷载的必要性、合理性、经济性。

In this paper, two general methods of equipment load applying are introduced, MPC method is used to conduct the error analysis of vertical equipment load. In the light of arrangement conditions of two equipment load on a slab in a nuclear plant, the increase of reinforcement amount by horizontal force, bending moment of equipment load is compared with reinforcement allowance of the slab, reliability of reinforcement and necessity, rationality and efficency of MPC method of equipment load applying are verified.
