Abstract:
Abstract An installation of post-drilled openings in existing reinforced concrete (RC) beams may result in an abrupt change in the beam’s cross-sectional dimensions, which could reduce the beam’s capacity and integrity of the beam. A variety of methods have been developed to adequately reinforce the area around the opening. This study investigates the efficacy of Carbon Fibre Reinforced Polymer (CFRP) sheets for strengthening RC beams with circular post-opening at shear zones. A total of five beams measuring 150 mm width, 300 mm depth and 1550 mm length were casted and tested under four-point

Abstract:
Deep beams, corbels, stepped beams, beams with openings and the like are structural members comprising discontinuous regions for which conventional flexural theory does not apply. To strengthen such members using fibre-reinforced polymer (FRP) systems, a rational approach based on strut-and-tie models (STMs) is desirable. This involves the strengthening of struts, ties and nodal zones where required. This study was carried out to illustrate the use of strut-and-tie models in FRP strengthening of reinforced concrete T-beams with a large opening created through the web. Five 3-meter long simply-

During the service life of a building structure, the introduction of web openings into existing steel floor beams is often required to allow for new services such as air conditioning, sprinkler systems, telecommunications etc. However, the presence of large openings in the webs can significantly reduce the shear and bending strength capacity of the beams. Traditionally, the welding of additional steel plates around the opening areas is adopted as a means of strengthening and stiffening.

The shear capacity of reinforced concrete pier caps in existing bridge support systems can be a factor which limits the capacity of an existing bridge. In their usual configuration, pier caps behave as deep beams and have the ability to carry load through tied arch action after the formation of diagonal cracks. Externally bonded fiber reinforced polymer (FRP) reinforcement has been shown to increase the shear capacity of reinforced concrete members which carry load through beam action.

Few decades ago, there were no guidelines for torsion design of reinforced concrete (RC) beams. Hence, many existing beams in older buildings have a lack of adequate torsional strength since they were not properly designed for torsion. One way to regain/rehabilitate adequate torsional strength is through application of externally bonded carbon fiber reinforced polymers (CFRP).

However, there was no linear relationship between the amount of CFRP sheets and the strengthening effect, and the load on the beams had a great impact on the rigidity of the beams in the yield stage.

Abstract:
Externally bonded FRP systems offer an attractive method to improve the fatigue life of steel beams. The fatigue performance of such a strengthened beam can be further enhanced by prestressing the bonded FRP reinforcement. While a number of studies have been conducted on the fatigue strengthening of steel beams using FRP, they have generally been concerned with the overall performance of the strengthened beam, with limited attention to the behaviour of the FRP-to-steel interface and its effects. Against this background, this paper presents the preliminary results of an ongoing experimental pro

Abstract:
Abstract Architected Instability-based Metamaterials (AIMs) composed of curved beams can exhibit multi-stable geometric phase transformations. By tailoring geometry and topology, AIMs can accommodate large reversible deformations while dissipating energy beyond the capabilities of conventional materials. These exceptional mechanical properties are attractive for aerospace engineering applications, including energy-absorbing components in landing gears, impact-resistant protective structures, and vibration-damping systems. Nevertheless, this very mechanism that enables reversible energy dissipa

Abstract:
One possible method for strengthening deteriorated concrete structures is to externally bond composite material plates to the concrete. The use of Carbon Fiber Reinforced Polymer (CFRP) laminates as an effective and versatile technique for strengthening reinforced concrete (RC) structures has developed into a sizable industry in recent years. To implement such rehabilitation, the nature of the bond between the composite plate and the concrete must be understood. The behavior of reinforced concrete beams strengthened in the negative moment region using CFRP strips is presented in this paper. Th

Abstract:
GFRP (Fiber Reinforced Polymer) reinforcement material is characterized by high strength and excellent corrosion resistance, which exhibits promising application prospects in engineering. The GFRP reinforcement for steel-concrete beams can increase the structural load-bearing capacity and durability. In this study, a refined finite element model of high-temperature GFRP-reinforced recycled steel-concrete beams was established by using ABAQUS software. The temperature distribution and residual load-carrying capacity of GFRP-reinforced recycled steel-concrete beams were analyzed, and the reliabi

Abstract:
In this paper, the joint parameters derived from testing the new fully-bolted core tube beam-column joint were utilized in the finite element analysis of the complete frame structure. The static elastic-plastic time-history analysis of 8, 12, 16, and 20-story steel frames with the braces was carried out. By comparing the maximum inter-layer displacement angles in the X and Y directions when the frame yielded, the rationality of the brace arrangement and the applicability of the new fully-bolted core tube beam-column joints in the multi-story and high-rise steel frames were confirmed.
