Finite Element Analysis of Moment Resisting Joint in Timber Frames
Subject area: Science,Engineering and Technology · Area of research: Civil Engineering
Abstract
An important responsibility of a structural engineer is to develop suitable arrangement of structural system that can withstand the most critical combination of load cases efficiently during the entire lifetime of the structure. The basic deterministic finite element analysis based on displacement-based finite element method using commercial software Staad.pro was used. The versatility of the software is, its ability to model different materials, differing structural configuration, and also capable of performing linear, nonlinear, buckling and pushover analysis. The essential need is to have a tool capable of predicting the state of stress and strain in any element of the structural system. To verify the accuracy of the analysis, a 25m span pitched timber portal frame made from glued-laminated (glulam) material was discretized and all the loadings (dead, imposed, snow and wind loads) applied. Using eight nodesisoparimetric type solid elements to realistically model the entire frame, the equilibrium condition of the elements within the joint area was captured. Thus, the critical shear capacity required for the design of joint in the frame was determined to be 29.047KN.
