. This paper presents our work on the integrated use of computational methods (e.g. geometric modeling, simulation, visualization and optimization) for structural analysis and design. The focus in this paper is on 3D solid modeling and dynamic simulation. The paper describes our program system comprising the in-house program FEM90 integrated with commercial(More)
The paper presents the development and application of software for structural analysis adapted to construction engineering applications. The software consists of data structures, application subroutine libraries and the built-in Matlab subroutine library. For each application, the user writes an application-specific main program using the data structures(More)
For finite element analysis of wave propagation in an elastic medium surrounded by an adjacent “infinite” region, the introduction of external boundaries introduces severe reflection problems, which may ultimately distort the solution. Analysis based solely on finite elements is not sufficient, as the boundary will add unwanted reflections to the grid. This(More)
