      This study tests ten full-size simple-supported beam specimens with the high-strength reinforcing steel bars (SD and SD) using the four-point loading. The measured compressive strength of the concrete is in the range of 70– MPa. The main variable considered in the study is the shear-span to depth ratio. Based on the experimental data that include maximum shear crack width, Cited by: 4. Beam-column connections have been identified as potentially one of the weaker components of reinforced concrete moment resisting frames subjected to seismic lateral loading. Well-established knowledge of RC joint shear behavior is necessary because severe damage within a joint panel may trigger deterioration of the overall performance of RC. An experimental study to investigate the shear strength of concrete beams without shear reinforcement (stirrups) and reinforced in the longitudinal direction with different types and ratios of FRP bars was carried out by the authors (El-Sayed et al. b). The investigation included nine full-scale reinforced concrete beams ( × × mm)File Size: KB. serlea IV T ••••••••••.. &oam IV T L (No ") Beam rv T ~ 2 (Stirrup" at. 12") Bu.. rv T ~ J (stirrup" at eo) DISCUSSION fF T.I';ST RESUl:rS.

Shear strength of two-span continuous reinforced concrete beams with multiple point loading. by Robert Henry Bryant Download PDF EPUB FB2

The failure plane of two-span continuous T-beams was formed unsymmetrically within one interior shear span only, along a diagonal crack connecting the edge of the loading plate and a point at a finite distance from the intermediate by: 8.

Fifty-two continuous reinforced concrete beams were tested under concentrated loads and the results analyzed in on effort to determine the following: (1) effect of continuity on the shear strength of statically indeterminate members, (2) contribution of web reinforcement to shear strength, and (3) to establish the minimum amount of web reinforcement required to prevent shear by: All beams have the same dimensions as shown in Fig.

total length is mm, the shear span is a = mm and the height to the width ratio is h/b = / specimens are sorted in three groups; Control specimens (2 beams without shear reinforcement), Group (3 beams) and Group (3 beams), as shown in Fig.

The test parameters were the type of U-shaped precast section (RC for NCS and HPFRCC for UCS), shear span ratio ( for UCS and for UCS), and spacing of shear Author: Xiangguo Wu, Thomas H.-K. Kang, Yang Lin, Hyeon-Jong Hwang.

Shear capacities of LSCC beams are found to be about 25% more than that of laced reinforced concrete (LRC) beams with a shear span to depth ratio ofwhile they are found to be equal to that. A new analytical approach for the evaluation of the shear strength of reinforced concrete beam-column joints with crossed inclined reinforcement is developed.

The proposed model considers that a joint member resists to the applied shear via three mechanisms, the concrete diagonal strut, the steel conventional shear reinforcement truss and the X Cited by:   Twenty-Four Two-Span Continuous Beams were tested to determine the manner and degree of moment and shear redistribution after yielding of the first critical section.

The adequacy of the minimum shear reinforcement provision in higher strength reinforced concrete beams was investigated. Eight rectangular beams with concrete compressive strengths in the range of to 10, psi and with web reinforcement indexes in the range of 0 to psi designed to fail in shear were tested.

In this paper testing of eighteen reinforced concrete beams without shear reinforcement is compared to three building codes; American Concrete Institution Building Code Requirements for Structural Concrete (ACI), European Standard Eurocode 2 and Model Code nominal shear resistance, Vn is provided partly by the concrete, Vc, and partly by the shear reinforcement crossing the failure plane, Vs.

In this study, we propose a new equation that evaluates the shear strength of beam–column connections in reinforced concrete and steel beam (RCS) composite materials.
