Abstract

The purpose of this study is to describe the effect of Reduced Beam Section in vierendeel panel element in STF system’s inelastic behavior based on earthquake load analysis. STF system is applied to 4, 6, and 10 storey building that served as office building. The structure’s system used Special Moment Resisting Frame (SMRF) system in longitudinal direction (W-E) and STF system in transversal direction (N-S). The analysis method that used in this study is nonlinear pushover analysis. Application of RBS in vierendeel panel element showed that by the increasing of storey number, the ductility of the structure was increased in both directions, while N-S direction has bigger ductility than W-E direction. Dissipation energy of the structure was also increased, especially in N-S direction. The first yielding process occurred in vierendeel panel element, and then followed by truss and diagonal chord around vierendeel panel element, while the critical condition showed still at life safety level.

Abstract

This paper describes the finite element procedure for modeling cold-formed steel bolted moment connection to simulate hysteretic moment-rotation behavior and failure mode. The connection element consists of CFS curved flange beams, double-lipped channel columns, and trough plates. Abaqus software is used in this paper. The modeling procedure includes material properties, bolt modeling, boundary conditions, mesh, loading, and geometrical imperfections. The results of the finite element modeling were compared with the experimental test results in the form of a back-bone of the moment-rotation curve and a comparison of failure deformation. It was found that the finite element results had fairly good accuracy in predicting the hysteretic moment–rotation behavior. In the elastic region, the result shows that the finite element model successfully simulates the initial stiffness of the referenced beam-column connection. Meanwhile, the peak moment of the finite element model occurs at the same rotation as the experimental test but the magnitude of the peak moment is lower than the experimental result, which indicates that the finite element model produces a more conservative design. The comparison of failure deformation between finite element model and experimental test shows a very good agreement. The numerical model can simulate well the rotational behavior of the beam-column connection and can predict the general shape and location of local/distortional buckling at the beam-column connection.

Abstract

The use of Reinforced Concrete (RC) deep beams in the building may require web openings or holes for electricaland mechanical utility passage. This web opening will change the behavior of the RC deep beam and may result in early crackseven at service load. Hence, it is important to use a suitable tool to predict the full response of the RC deep beam with theopening. For that purpose, a nonlinear finite element method using 3D-NLFEA software package which utilizes a plasticityfracture model is used to predict the behavior of RC deep beam. One deep beam specimen available in the literature isinvestigated. To study the effect of using structured and unstructured mesh, as well as different element types on the loaddeflection curve, the hexahedral and tetrahedral solid element was used. From the comparisons, it was observed that the crackpattern between two different meshes was not similar. Structured mesh often has straighter crack propagation compared to theunstructured mesh. The load-deflection curve for both models is similar and both models were performed satisfactorily inpredicting the peak load of the deep beam.

Abstract

A multi-level modeling and simulation method of structural system using grid-computing framework is proposed in this paper. Two levels of parallel processing will be involved in this framework: (1) multiple locally distributed computing environments connected by the local network to form (2) a grid-based cluster-to-cluster distributed computing environment. To successfully perform the simulations, a large-scale structural system is decomposed into the simulations of a simplified global model and several detailed component models with various scales. These correlated multi-scale simulation tasks are distributed amongst clusters and connected together in a multi-level modeling and simulation method and then coordinated over the internet. This paper also presents the development of a grid-computing software framework that can support the proposed simulation approach. The architectural design of the program also allows the integration of several multi-scale models to be clients and servers under a single platform. Additionally, the comparison result between proposed method and assumed exact solution show that the proposed simulation method is appropriate to simulate the response of the structural systems.
