Abstract: A 3 stories and l/3 reduced scale concrete-filled tubular steel column-staggered truss structure model was tested under lateral load. A command stream of finite element analysis for the model is edited with the ANSYS Parametric Design Language APDL and the calculated results are much coincided with those of the test. Model of finite element and command stream are corret. The command stream was used to analyze the behaviors of concrete-filled tubular steel column-staggered truss structures with the different shape section of column, stiffness of truss, high-to-span ratio, type of truss and eccentric load.
