Abstract:

The dynamic behavior of a PPSRC beam–column joint is related to constraint effect, strength deterioration and strain rate effect. Then, it can be assessed by bearing capacity, stiffness degradation, displacement ductility and energy consumption. The results show that the increased strain rate causes growth in ring stiffness, bearing capacity and energy consumption of PPSRC beam–column joints. However, the influence of shear span-to-depth ratio on dynamic mechanical properties of PPSRC beam–column joints is more obvious than that of strain rate. Regardless of strain rate, the bearing capacity,

Abstract:

The shear span-to-depth ratio has the most significant influence on the shear capacity of beams and determines their failure mode. The subject of the current project is the shear capacity of precast posttensioned concrete crane beams disassembled after more than fifty years of being used in an industrial plant. The paper gives the theoretical basis for the shear capacity of such elements as well as standard design models. The conducted tests showed that despite the low shear reinforcement ratio, the elements do not fail in a brittle mode but show a clear indication of prospective destruction.

Most of the prediction models for the shear capacity of FRP bar reinforced concrete beams without web reinforcement in current codes are reported to be conservative and do not consider the effect of span-to-depth ratio.

Abstract:

Reinforced concrete deep beams are known to display complex behaviour. This is due to their exceptionally high beam depth when compared to normal shallow beams. Their strength capacity is mainly governed by their shear strength due to their geometric proportions. It is also governed by a number of parameters, which include size of the beam, strength of the concrete used, placement and amount of tensile and web reinforcement used and the shear span-to-depth ratio. While a lot of research has been conducted on how these parameters affect the shear strength of deep beams, this study aims to find

All slabs were cast with a high compressive strength concrete of approximately 79.5 MPa. Experimental test results showed four patterns of failure mode depending on the ratio of (a/d).

The aim of this study was to investigate the dynamic shear failure behavior of RC beams under rapid loading through an experimental study. Thus, rapid loading test for 48 RC beams was performed, in which shear span-to-depth ratio, shear reinforcement ratio and loading rate were variable. The RC beams exhibited diagonal tension failure, shear compression failure and flexural failure depending mainly on the shear span-to-depth ratio and the shear reinforcement ratio. The influence of loading rate on the maximum resistance is more significant for the RC beams failed in shear than for those failed

The present research is conducted to investigate the structural behaviour of continuously supported deep beams made with SCC. A series of tests on eight reinforced two-span continuous deep beams made with SCC was performed. The main parameters investigated were the shear span-to-depth ratio, the amount and configuration of web reinforcement and the main longitudinal reinforcement ratio. All beams failed due to a major diagonal crack formed between the applied mid-span load and the intermediate support separating the beam into two blocks: the first one rotated around the end support leaving the

To cater engineering application needs, cold-formed steel (CFS) members often have some web openings which could influence bearing capacity of the steel beam under combined bending and shear action. This paper presents tests on 20 groups of thin-walled web-perforated lipped C-shaped CFS beams, which were conducted under single point loading mode at mid-span. Besides, detailed finite element parameter analysis on the high shear-span ratio (a/h= 1.5 ~ 4.0) specimens was conducted by ABAQUS after the model was verified, which was mainly focused on the influences of different hole depth-to-web hei

Abstract:

Shear deformation may significantly affect the structural behaviours, especially for the structural members with small span-to-depth ratios. It is vital to consider the shear effects in the Direct Analysis Method (DAM) of thin-walled structures such that only the section capacity check is required in the evaluation of both member and system stability. However, there is lack of a general method to determine the shear correction factors of thin-walled cross-sections in various shapes and as a result DAM cannot be applied to the structures adopting these cross-sections. This paper proposes an inn
