Finite element analysis of reinforced concrete deep beam with large opening

Abstract Background A series of nonlinear finite element (FE) analyses was performed to evaluate the different design approaches available in literature for reinforced concrete deep beam with large opening. Three models were developed and analyzed using computer software ATENA. The three FE beams made details based on approaches: (Kong, F.K. Sharp, G.R., Magazine Concrete Res_30:89-95, 1978), (Mansur, M. A., Design web openings, 2006), Strut Tie method (STM) as per ACI 318-14 (ACI318 Committee, Building Code Requirements Structural (ACI318-14), 2014). Results from compared effect reinforcement structural behavior transfer service load deflection is same models. stiffnesses designs 2006) STM reduce at a higher than ultimate while 1978) reduces stiffness close load. designed according model starts cracking method. detailed failed due extensive shear cracks. specimen restores its capacity after initial failure. satisfy limit. Conclusion It found that give sufficient capacity. amount given by both same. used other two methods. Additional needed limit crack widths. (2006)) gives lesser steel requirement failure
