Based on the reinforced concrete beam structure bonding with steel plate are consisted of different materials, the finite element model of the reinforced concrete beam structure bonding with steel plate was established using the whole model and the separated model respectively, the deformation, stress, strain and limit load of the reinforced concrete beam structure under the symmetrical concentrated load and the uniformly distributed load were studied using ANSYS. The research results show that the limit load value based on the finite element simulation is basically equal with the experimental value, there has little error between them, but within the scope of control in error, and the limit load under the uniformly distributed load is greater than the symmetrical concentrated load; The results from the whole model and the separated model are basically equal with the experimental results, which show that it’s feasible using the finite element simulation to analyze the reinforced concrete beam structure bonding with steel plate.

Reinforced Concrete Frame Structures

Reinforced concrete (RC) frame structure is one type of building structure which is widely used in China. Damage of some reinforced concrete frame structures under the earthquake is caused by the damage of beams and columns, so beams and columns are essential seismic members. However, the test datum are not enough to study the performance of RC beams and columns , Therefore, Finite element simulation of RC beams and columns is performed by software ABAQUS in the paper. Through comparing with the finite element simulation and the test of load - displacement skeleton curve, failure mode and steel bar strain, the result shows that the finite element simulation can more accurately simulate the situation of the test and verifies the finite element simulation is the most important research tool besides test.

Reinforced Concrete Frame Structures

The characteristics of the shear deformation inside the beam-column joint core of reinforced concrete frame structures subjected to seismic loading are discussed in this paper. The paper presents the formulation of an analytical model based on experimental observations. The model is intended to predict the expansions of beam-column joint core in the horizontal and vertical directions. The model describes the strain compatibility inside the joint in an average sense. Its predictions are verified utilizing experimental measurements obtained from tests conducted on beam-column connections. The model is found to adequately predict the components of shear deformation in the joint core and satisfactorily estimates the average strains in the joint hoops up to bond failure. The model may be considered as a simple, yet, important step towards analytical understanding of the sophisticated shear mechanism inside the joint and may be implemented in a controlled-deformation design technique of the joint.

This paper presents an investigation into the flexural behaviour of reinforced concrete beam with opening reinforced with two different materials i.e., steel and Glass Fiber Reinforced Polymer (GFRP). Comparison study between the two different materials were carried out and presented in this study through non-linear Finite Element Method (FEM) using the commercial ABAQUS 6.10 software package. The performance of the opening beam reinforced with GFRP is influenced by several key parameters. Simulation analyses were carried out to determine the behavior of beam with opening subjected to monotonic loading. The main parameters considered in this study are size of opening and reinforcement diameter. The results show that GFRP give 23%-29% more ductility than steel reinforcement. The result also shows when the size of opening change from 200mm to 150mm or from 150mm to 100mm the ultimate load capacity increase by 15%. In general, good agreement between the Finite Element (FE) simulation and the available experimental result has been obtained.

Many engineering facilities are severely damaged by blast loading. Therefore, many manufacturers of sensitive, breakable, and deformed structures (such as facades of glass buildings) carry out studies and set standards for these installations to withstand shock waves caused by explosions. Structural engineers also use these standards in their designs for various structural elements by following the ISO Damage Carve, which links pressure and Impulse. As all the points below this curve means that the structure is safe and will not exceed the degree of damage based on the various assumptions made. This research aims to derive the Iso-Damage curve of a reinforced concrete beam exposed to blast wave. An advanced volumetric finite element program (ABAQUS) will be used to perform the derivation.
