design of shear reinforcement using a strut and tie model considers the flow of forces in a reinforced concrete element that is a series of compressive strutRizk, EMarzouk, HTiller, RProceedings, Annual Conference - Canadian Society for Civil Engineering...
Shear strengthening of RC beams or bridge girders in old RC structures is one of the most common needs when assessing their strength under the current code requirements (e.g. Eurocodes [29]). This is due to insufficient amount of shear reinforcement, corrosion of existing shear reinforcement, ...
It is found that there is a decreasing linear relationship betweencotθandlnω, wherelnωis the natural logarithm of the mechanical shear-reinforcement ratio. On this basis, a new shear design equation is proposed for slender RC beams with stirrups, which is shown to be not only simpler, ...

Experimental Study on Seismic Behavior of Lightweight Concrete-Filled Cold-Formed Steel Shear Walls Strengthened Using Horizontal Reinforcement increased the shear strength, lateral stiffness, and energy-dissipating capacity, whereas installing the coupling-section interior studs enhanced the ductility. ... ...
The overall aim of this paper is to develop a unified design method for the punching shear resistance of slab-column connections irrespective of the type of internal reinforcement. In the first part of the paper a design model for the punching shear resistance of concrete slab-column connections...
in depth. Previous research had indicated that as the depth of a beam without shear reinforcement increases, a decrease in the shear strength of the section can be expected. This phenomenon has been termed as size effect and should be considered. In other words, the size effect of beams ...
Myy=Myy+0.5(d–d')Nyy and Mxy=Mxy +0.5(d–d')Nxy. The shear design is based on the shear force acting on the critical section where the required shear reinforcement is maximum.关键词: reinforced concrete plate biaxial force biaxial bending flexural shear design ...

Direct design method is an analytical method by which the required area of reinforcement for short reinforced concrete columns or shear walls is directly calculated without using interaction diagrams. Some other advantages of this method are: Mustafa Mahamid ACI member, currently a Clinical Associate ...
