29. Mai 2024 · 112 Accesses. Metrics. Abstract. Precast concrete structures have developed rapidly because they meet the requirements of green and low-carbon social development. In this paper, a precast...
16. Mai 2024 · Post-installed (PI) reinforcing bars (rebars) are commonly employed in concrete-to-concrete connections to rehabilitate, extend, and strengthen reinforced concrete (RC) structures or replace damaged or misplaced rebars.
Vor 6 Tagen · Dynamic behavior of elastically supported bidirectional functionally graded (BDFG) beams resting on an elastic foundation under a moving harmonic load is investigated based on Chebyshev collocation method. Material properties of the BDFG beam are assumed to vary along the length and thickness of the beam according to a power-law ...
14. Mai 2024 · Cabrero et al. [ 3] carried out experiments on extended end-plate beam-to-column symmetrically loaded joints in both major and minor axes, the results showed that with increasing the thickness of the endplate, both the moment resistance and the rotational stiffness of the joint were improved.
13. Mai 2024 · The results show that the beam end of the steel beam weakened flange and weakened web opening-type specimens bear the majority of the deformation and energy dissipation of the whole joint, while the panel zone participation in the energy dissipation of the web opening-type specimens T14-BWW-1 and T14-BWW-2 accounts for a much smaller ...
Vor 4 Tagen · The beam-end connections were reinforced perpendicular to the wood grain using six STS and exposed to elevated temperatures that followed the CAN/ULC S101-19 standard fire time-temperature curve while subjected to a load ratio equivalent to 60% of the maximum design moment of the weakest unreinforced connection configuration.
8. Mai 2024 · To explore and compare the failure modes, deformation behaviors, and load-bearing capacities of single-edge notched (SEN) beams strengthened with carbon fiber-reinforced polymer (CFRP) and steel bars, static and dynamic three-point bending tests on both types of concrete beams have been carried out in this study. During the static ...
