The response analysis of reinforced concrete (RC) structures subjected to strong earthquake motions requires material models that are able to simulate cyclic deformation and damage realistically. This paper presents the results of a study of pinching and softening behaviour in an RC frame subjected to cyclic loading. The experiment was conducted on a full-scale RC frame at Indian Institute of T...

The results obtained from nonlinear fiber element analyses for concrete filled tubes (CFT) are discussed. The studies were aimed at assessing primarily the overall behavior and stability effects on these structural elements as a prelude to a large full-scale testing program. The study focuses on ultimate strength analyses for CFT composite columns with different stress-strain models for both co...

The complex response characterizing elastomeric isolation bearings is reproduced by employing a novel uniaxial hysteretic model that has been recently formulated and successfully implemented in OpenSees. Such OpenSees material offers several advantages with respect to differential models typically available commercial software products for structural analysis, such as 3D-BASIS CSi programs. Fir...

The superimposed slab shear wall has been found to be more and applicable in the building construction industry due its industrialization superiority. hysteretic behavior of walls accounts for an important part seismic performance analysis. This paper presents results a numerical study investigate walls. Different calculation methods capacity combined interface horizontal connection are introdu...

Original scientific paper RC frame structures with specially shaped columns and RC frame structures with rectangular columns are different types of structures with different column sections. A progressive collapse analysis model of RC frames was proposed using the beam-column element and joint element based on the program OpenSees. Progressive collapse performance of the experimental frame was ...

This paper presents an effective reliability analysis procedure and proposes the system resistance factors for design of steel-concrete composite frames that comprise concrete-filled steel tubular (CFST) columns beams. Advanced is employed to predict ultimate using fibre beam-column elements in OpenSees. The obtained predictions load-carrying capacity compare well with experimental results mean...
