4th INTERNATIONAL OPENSEES SHORT COURSE

Seismic Analysis of Structures using OpenSees:
Finite Element-based Framework and Civil Engineering Applications

The Hong Kong Polytechnic University

EVENT DESCRIPTION

OpenSees (Open System for Earthquake Engineering Simulations) is an open source software mainly conceived for the seismic analysis of structures. The source code is public in order to facilitate its wide diffusion and to be adaptable to the needs of users, who can also modify and extend default libraries in terms of materials, components, and algorithms. The main difficulties that users usually face during their first approach to OpenSees are due to the programming language, which might appear rather complex. Following previous editions, the main goal of this short course is to provide a basic understanding of finite element-based theoretical framework and programming language in OpenSees. Structural engineering applications will be also presented.
