碩士 === 國立中央大學 === 土木工程研究所 === 91 === The behaviors of reinforced concrete (RC)
structures containing brick wall under earthquake loading are quite complicated. It is very difficult to analyze the problem analytically. Experiment and numerical simulation are two possible solutions to extract reference information for the development of design code.
However, the experimental approach requires much effort and expense to built very limited number of specimens to explore the behaviors of RC structures. The main advantage of using numerical simulation code to study the structural problem is that any detail response of the system can be detected easily from the calculated data.
In this study, a computation code is developed to simulate the nonlinear dynamic behaviors of RC structure containing brick walls. Both the finite element method (FEM) and the discontinuous deformation analysis (DDA) were adopted to built up the numerical analysis procedure. Two-dimensional solid elements are used to model the concrete and brick and mortar materials and truss elements are used to model the reinforcement. The joint effect between the mortar and brick is modeled by joint element. The elastic-plastic response of reinforcement is considered in the
analysis. An equivalent strain model that can characterize the nonlinear loading and unloading behavior of concrete material is applied. To simplify the analysis of cracked elements, the smear crack model and associated damage theories were used for the material points satisfying failure criteria.
The accuracy and effectiveness of this newly developed simulation code were verified by the matching between numerical prediction and experimental result of various cases. The hysteresis load-displacement response for a RC frame can be calculated that is very helpful for the seismic analysis and retrofitting design.
