A 3D finite element (FE) analysis technique using ABAQUS is chosen to explore the dynamic behavior of a beam under impact load. A beam, for which the impact dynamic test was conducted by Kishi (2004), is selected to develop a solid element FE model. FE analyses were performed implementing ABAQUS Explicit (2004) programming tool to predict the dynamic responses under the pressure amplitude intro...

The problem of damage accumulation in fiber-reinforced concrete to structures supporting underground workings and tunnel linings against dynamic loading is insufficiently studied. mechanical properties were determined the mechanism destruction with different reinforcement parameters described. Concrete Damaged Plasticity model for at are based on results lab experiments. Numerical simulation co...

In this paper, the finite element simulation software ABAQUS was used to study hysteretic performance of Q690 high-strength steel (HSS) and high-web box-section columns. The model established by solid elements, influence initial defects materials on specimen considered. hyteretic conducted analyzing comparing width-thickness ration flanges webs. results show that increase ratios webs will reduc...

Concrete is a versatile material having number of desirable properties, so widely preferred in construction industry. But major disadvantage that under severe vibrations such as earthquakes it gets cracked and concrete has poor modification repair quality. Therefore some or strengthening must be performed damaged element stand for further useful life. Many civil structures are no longer conside...

The antique building combines traditional design with contemporary technology, making it an important structural style. Columns, as a crucial component, directly affect how well the functions whole. This paper proposes new connection form upper square concrete-filled steel tube-lower circular tube (USCFST-LCCFST). study investigates seismic performance of proposed columns. First, finite element...

An alternative remeshing methodology for 3D Abaqus explicit analyses which utilizes mesh mapping is presented. Excessive element distortion in 3D large deformation analyses necessitates remeshing, however in Abaqus explicit, the standard 3D remeshing techniques limits the analyst’s choice of element type. The presented technique allows remeshing of 3D perfectly plastic fully integrated higher o...
