A STUDY ON ULTIMATE STRENGTH OF REINFORCED CONCRETE SHEAR WALLS AFTER FLEXURAL YIELD

Shear and Flexural Stiffnesses of Reinforced Concrete Shear Walls Subjected to Cyclic Loading

Seismic analyses of concrete structures under maximum-considered earthquakes require the use of reduced stiffness accounting for cracks and degraded materials. Structural walls, different to other flexural dominated components, are sensitive to both shear and flexural stiffness degradations. Adoption of the gross shear stiffness for walls in seismic analysis prevails particularly for the design...

Experimental Investigations on The Flexural Strength of PET Reinforced Concrete

Due to the rapid industrialization taking place globally, the problems generated are acute shortage of construction material and increasing in productivity of wastes. The production and consumption of plastic and the rate at which solid plastic waste (SPW) are created have increased considerably. Plastics constitute 12.3% of total waste produced most of which is from discarded water bottles. Th...

Experimental Study on Flexural Behavior of Precast Concrete Shear Walls with Vertical Joint

A Macro-model for Nonlinear Analysis of 3D Reinforced Concrete Shear Walls

Architectural limitations in many situations make it necessary for the RC shear walls to be extended in plan in different directions at a single location that makes them a 3D configuration. Analysis of such walls is very challenging. In this research about 450 cases of 3D shear walls are considered with different shapes and heights. L, T and H-shape walls are studied. They are nonlinearly analy...

Shear strength model of reinforced concrete circular cross-section members

A shear capacity model of reinforced concrete members with circular cross section transversely reinforced with circular hoops has been developed. The proposed model is based on the truss analogy by adding a concrete contribution term to the capacity of the shear reinforcement. An additional deviatoric shear resisting th c curv pres nism ste ved und ctor mechanism of hoops present solely in memb...
