Numerical Analysis of Arch Reinforced Concrete Deep Beams with Various Cross Sections

Abstract

Beam member is one of the important components in a building structure with the functions to transfer loads to column and foundation. The main purpose of this study is to determine the effect of cross-section arch deep beam structure with a different type of cross-section. The deep beam in this study consists of two types of longitudinal versions called non-arch and deep arch beam. Besides, and four different cross-sections are applied as a variation to investigate the effect of cross-sections on flexural behavior. This study only used finite element analysis to investigate the stress distribution, load, and displacement relationship, ductility, and stiffness of the model. The loading used in this analysis is in 4 points where the load is located at 1/3 and 2/3 of the span. The results show that the deep arch beam experience a decrease in flexural performance compared with the normal deep beam. Deep beam with rectangular section produced high performance compared with other cross-sections. However, the damage pattern indicates that shear failure is still dominant in all models.
