In order to study the shear behavior of reinforced light weight Concrete (LWC) and Normal-weight Concrete (NWC) simply supported deep beams with and without web openings an analytical program has been conducted. The results have been used to examine the applicability of the shear design requirements of three international codes (ACI 318-02, ECCS-2001, and EC-2).The behavior of the deep beam is examined by the use of finite element software ANSYS. The test program included seven reinforced concrete simply supported deep beams. The main parameters examined were the size and position of opening, the design concrete compressive strength, the magnitude of transverse reinforcement ratio and span-to-depth ratio. The results indicated that the presence of web openings (of height equal to 20% and 40 % of the total web height, respectively) in the load path leads to a reduction in the ultimate shear strength of LWC simple deep beams by about 10 and 55% when compared with a similar beam without opening. |
