NUMERICAL MODELING of COMPOSITE STRUCTURES: COMPARISON BETWEEN ANALYTICAL and EXPERIMENTAL RESULTS
This paper presents the numerical modeling of beam-column sub-assemblages using computer software Drain-2dx. Two beam-column sub-assemblages tests are presented in this paper, called Specimen 1 and Specimen 2. The result of the computer simulation is compared with the result of the experimental test.. The computer model developed was then used to model a three-dimensional steel-concrete composite structure. Comparison between the results of the pretest analysis and the experimental results show that in general, the computer model developed for steel-concrete composite frame using the computer SoftwareDrain-2dx is quite accurate. The small difference between the results is mainly due to the fact that the hinge connections are in fact work as semi-rigid connections due to the presence of concrete slab which could transfer forces from beams to columns. The semi-rigid connections are usually neglected in the computer model.
