The research of this dissertation has two main aspects, which are the
theories of analysis and design of prestressed concrete slabs with finite
element method, the developing of a program for designing prestressed
concrete slabs. At last, the function and design process of the program
have been shown with a practical project.
For prestressed concrete slabs ,the level force of prestressed
reinforcement make prestressed concrete slabs produce plane stress while
bearing the action of the bending of plates, which lead prestressed
concrete slabs to be a shell model in fact. Aiming at applying shell
elements, this paper detailedly discusses the general method and process
of analysis for prestressed concrete slabs with shell element, and program
compiled with the basic principle to analyze and design prestressed
concrete slabs.
This program adopting an object-puter language,
provides the users with an interface for design of prestress concrete slabs,
which can finish modeling internal force calculation graphics post
process etc.
