...Gani Arachchige Thulithi Kaumadi Ganiarachchi; Senanayaka Vidhanage Thilanka Janaka Perera The aim of this study was to elucidate the unexpected reduction in the diagonal shear strength of high-strength concrete (HSC) beams with an increase in concrete strength. The modified compression field...

...Ping Li; Liu Jin; Xiuli Du Very few studies have been dedicated to the size effect on the shear behaviour of reinforced concrete (RC) columns. In particular, there lacks a design equation that can quantitatively represent the effect of related parameters on the size effect on nominal shear strength...

.... The test results show that the shear strengths of deep beams made with high-strength concrete were higher than the shear strengths of deep beams made with normal-strength concrete. In addition, the shear strengths of deep beams with circular openings were found to be higher than those of deep beams...

..., the reduction of the nominal size and coarse aggregate content in the concrete mix may adversely affect its shear strength. Therefore, the aim of this research was to evaluate the shear strength of SCC by means of push-off tests of 45 specimens, produced with one conventional concrete and two SCC mixtures...

...Dimitrios K. Zimos; Panagiotis E. Mergos; Vassilis K. Papanikolaou; Andreas J. Kappos Older existing reinforced concrete (RC) frame structures often contain shear-dominated vertical structural elements, which can experience loss of axial load-bearing capacity after a shear failure, hence initiating...

..., it is still an average value within the intervals of two adjacent gauges (Lee and Mulheron, 2015). Moreover, it is known that the bond stress is distributed more uniformly as the bond length becomes shorter, and the bond stress actually refers to an equivalent shear stress for deformed bars. Therefore...

... this pattern is more conducive to concrete casting than a bunched square reinforcement pattern. The softened strut-and-tie model more accurately predicts the ultimate load for pile caps than the ACI sectional method for various shear span-to-depth ratios and compressive strengths of concrete. The ACI sectional...

...Abobakr Elwakeel; Robert Vollum The shear resistance of reinforced concrete beams is enhanced by arching action when loads are applied to their top face within around twice the beam effective depth (d) of the supports. Previous experimental investigations into shear enhancement have almost...

..., and the concrete refers to all types of cementitious materials. Fracture & fracture mechanics Reinforcement Shear Accepted manuscript doi: 10.1680/jmacr.21.00013 Accepted manuscript As a service to our authors and readers, we are putting peer-reviewed accepted manuscripts (AM) online, in the Ahead...

...Ngoc Thanh Tran, PhD; Duy Liem Nguyen, PhD; Dong Joo Kim, PhD; Tri Thuong Ngo, PhD In this study, shear resistance of ultra-high-performance fibre-reinforced concrete (UHPFRCs) containing different types (smooth, hooked and twisted fibre), fibre aspect ratios (l/d = 100, 95 and 65...

...Naser S. Alimrani; Gyorgy L. Balazs The behaviour of concrete reinforced with steel fibres at elevated temperatures was investigated in terms of shear deterioration. Using three different steel fibre contents (0, 40 and 80 kg/m³), 45 push-off specimens were tested at five maximum...

... of the wall and the footing, longitudinal prestressed steel strands, L-shaped steels and infilled high-strength grout. One monolithic shear wall specimen and five precast specimens were tested under simulated seismic loads. The test parameters studied included the presence or absence of L-shaped steel...

...Mohammad Sadegh Barkhordari; Mohsen Tehranizadeh; Michael H. Scott In recent decades, different macro-models have been proposed for simulating the behaviour of concrete shear walls because of their significant role in the seismic performance of urban buildings. The ability of Timoshenko's beam...

...Nagavedu Jayakumar Yogalakshmi; Kanchi Balaji Rao The complexity in the shear behaviour of reinforced concrete (RC) beams increases with a decrease in the shear span to effective depth ratio (a_v/d) because of the increase in the contribution of concrete to the shear...

...Deuckhang Lee; Sun-Jin Han; Hyunjin Ju; Dichuan Zhang; Kang Su Kim This study aims to develop a shear strength model for steel-fibre-reinforced prestressed concrete (SFR-PSC) beams. A dual potential capacity model was adopted to consider the shear-resistant mechanisms of the compression and cracked...

... for unidirectional earthquake actions. To date, detailed calculation methods for the shear capability and shearing performance of joints in RC frames under arbitrary horizontal direction loading have not been reported. For this reason, in this work, the shear mechanism of beam–column joints in an RC frame under...

...Mohamed K. Ismail; Assem A. A. Hassan The shear behaviour of large-scale engineered cementitious composite (ECC) beams reinforced with different types of fibre was evaluated. Four types of fibre were used: 8 and 12 mm long polyvinyl alcohol fibres (PVA8 and PVA12), 19 mm long polypropylene fibres...

...–column connection. Isolated punching tests are valuable in order to analyse the punching shear behaviour systematically. Nevertheless, beneficial effects of slabs' continuity (e.g. moment redistributions and membrane actions) may not occur in these tests. To investigate the punching shear behaviour...

... self-weight, usable area and, potentially, costs. However, in comparison with conventional reinforced-concrete beams, there are fewer studies on post-tensioning SFR-RPC beams subjected to shear failure. In this study, a series of shear tests for four large-scale beams (one SFR-RPC beam and three post...

...Dominik Kueres; Josef Hegger According to previous investigations, prestressing has various positive influences on punching shear behaviour of reinforced-concrete slabs. While in-plane compressive stresses and decompression moments reduce the slab deformations, leading to an increased punching...
