Abstract:
This paper is concerned with the analysis of quadratic parabolic shallow shels by means of the finite strip method (FSM).The curved strip element can be used to analyse the shell, in which the cuvature is larger in one direction. Through degeneracy, it can be used to solve doubly curued shallow shells, cylindrical shell and folded plates etc. Two FORTRAN programes are given on micro computer for the static and dynamic calculation. A series of shells, including positive, negative and zero Ganssian curvature shallow shells are analysed. Several static and dynamic experiments have been done for doubly curved saddle shells. The theoretical results are agreeable with the test data. Comparing with the finite element method, FSM has some advantages, such as higher precision, less computer time and less compter storage reguirements etc. It can be seen, many problems can easily be solved on micro computer by FSM.
