A large data base available has been segregated and a nonlinear regression analysis (NLRA) has been performed for developing the refined design models for both, the cracking and the ultimate shear strengths of reinforced concrete (RC) beams without web reinforcement. The shear strength of RC ...

Thirty-two beams made of normal- and high-strength concrete were tested to study the effects of web reinforcement placement on load-carrying capacity. Sixt... SH Ahmad,F Park,K El-Dash - 《Magazine of Concrete Research》 被引量: 35发表: 1995年 Shear Capacity of Reinforced High-Strength Con...
Institute of Structures, National University of Tucumán摘要 Experimental research shows that the addition of ductile fibers improves the tensile strength, ductility and concrete's energy absorption capacity. As a consequence of the improvement of the post-cracking behavior, the addition of dispersed duct...
The University of Texas Prestressed Concrete Shear Database (UTPCSDB) includes results from more than 500 shear tests conducted over the past 55 years. The bias of various code provisions to variables such as the compressive strength of concrete, member depth, transverse reinforcement ratio, and ...
In shear wall structures, not only the lateral loads and in-plane moments exerted by earthquake or wind but also the vertical loads due to gravities are mainly resisted by shear walls. Since the ductility of steel is better than reinforced concrete under earthquakes because of their material ...
This is due to insufficient amount of shear reinforcement, corrosion of existing shear reinforcement, low concrete strength and/or increased design load. Shear strengthening of RC beams with TRM jacketing has been investigated by several researchers in the last decade [1,[29], [30], [31], [...
This paper discusses modelling,analysis and design issues for a 55-storey hotel building recently planned for New York City,USA.The lateral force resistance of the investigated building primarily makes use of exterior reinforced concrete shear walls in one direction and exterior reinforced concrete ...
shear strength contributions provided by the diagonal concrete strut and the web reinforcement is derived, while considering those variables that significantly affect the behaviour of such walls. Model parameters were calibrated using the experimental results of 664 rectangular and flanged walls available ...
