HighlightsThe paper provides experimental results for two built-up steel columns and relevant semi-continuous base-plate connections.Experimental results highlight similarities and differences in cyclic lateral-load response of the two types of columns.Finite element models are also presented and analysed, comparing numerical results with experimental findings.The numerical study highlights effects of two typical modelling uncertainties: 1) anchor pre-stress; 2) grout properties.Eventually, the paper discusses importance of modelling anchor hook deformations for the two tested specimens.
AbstractThe paper describes and discusses results from both physical and numerical tests on lateral-load response of built-up battened steel columns with semi-rigid and partial-strength base-plate connections. Two specimens reproduced different case studies derived from two existing industrial steel buildings designed and built in the 1970s and 1990s respectively. First, multiple monotonic lateral-loading tests were carried out in the elastic range of response by varying the concomitant axial force. Subsequently, each specimen was tested under cyclic lateral-loads in the inelastic range of response for a selected value of the axial force. Following discussion and comparison of physical test results on the two specimens, the paper illustrates finite element (FE) model simulations of the physical tests. Focus of the numerical study is on highlighting modelling uncertainties, which engineering applications should consider in seismic assessment of existing buildings.
