Analysis of RC Structures Subjected to Multi-Directional Shear Loads
Source abstract
Abstract
The true behavior of many large complex structures involves interaction between the in-plane and transverse shear loads acting on the reinforced concrete (RC) element. This paper presents a model using a fiber-based finite element formulation to predict the strength of reinforced concrete members subjected to multi-directional shear loads. The shear mechanism along the element is modeled by adopting a Timoshenko beam approach. The nonlinearity of the concrete and steel materials is accounted for at the fiber level through the use of proper constitutive laws. The concrete constitutive law is based on the Softened Membrane Model (SMM), which was modified to account for transverse shear load effects. The modification of the concrete model is derived based on the findings of an extensive experimental program. The validity of the finite element model is established by correlation of analytical results with experimental tests of RC specimens subjected to multi-directional loads and available in the literature. These numerical studies showed that the model can accurately predict the reduction in strength due to the effect of transverse loads.
