The Application of CAD Technology on the Design of Reinforced and Prestressed Counterforce Wall System

Abstract:

The counterforce wall and pedestral is a complex system. Computer aided design technology is used to design and analyze this reinforced and prestressed concrete structure. Firstly CAD design program is used to design a representative wall section as a separate component. It helps doing ultimate limit state calculation and serviceability limit state checking computation. The prestress on concrete induced by prestressing steel according to construction method is also computed. Secondly, a finite element program is used to analyze the whole system. The prestress computed by CAD design program is regarded as external load. Simulation technology is also described in this paper. The stress, strain and deformation of the whole prestressed system are calculated and checked. Moreover, dynamic structural analysis is done by finite element program. Then vibration frequencies and modes can be obtained. By combining CAD design with finite element program, this complex system can be designed reasonably and effectively.
