This paper presents an efficient computer method for nonlinearinelastic analysis of threedimensional composite steel-concrete frameworks. The proposed formulation is intended to model the geometrically nonlinear inelastic behaviour of composite frame elements using only one element per physical member. The behaviour model accounts for material inelasticity due to combined bi-axial bending and axial force, gradual yielding is described through basicRead more
With the rapid advancement of computer technology, research is currently in progress to develop advanced nonlinear inelastic analysis methods and integrate them into the new and more rational advanced analysis and design procedures [1,2,3,4,5]. This paper presents an integrated system for advanced structural analysis and seismic performance evaluation of three-dimensional steel frameworks with rigid or flexible connections. The nonlinear inelasticRead more
This paper presents an efficient numerical procedure for the rapid design of arbitrary-shaped composite steel-concrete cross-sections that are subjected to biaxial bending and axial force. The design procedure allows cross-sections to be designed by solving directly for the reinforcement required to provide a cross-section with adequate strength. The new numerical procedure developed in this paper shows very good stability in the presence of strainRead more

A new incremental-iterative procedure based on the arc-length constraint equation is proposed in order to determine both interaction diagrams and moment capacity contours for composite steel-concrete cross-sections. This procedure adopts a tangent stiffness strategy for the solution of the non-linear equilibrium equations thus resulting in a high rate of convergence. The proposed approach has been found to be very stable for all cases examined hereinRead more
This paper presents an integrated system for advanced structural analysis and seismic performance evaluation of 3D steel frameworks with rigid or flexible connections. The non-linear inelastic static analysis employed herein uses the accuracy of the fibber-finite elements approach for inelastic frame analysis and address its efficiency and modeling shortcomings through the use of only one element to model each physical member of the frame. The proposedRead more
