This study evaluates the effect of shear on deflection reinforced concrete (RC) beams subjected to combined bending and shear. A total nine simply supported were manufactured with span-to-depth ratio, tension steel capacity ratio as test variables. The experimental results used evaluate by separating them into flexural deformations. theoretical specimens was calculated using effective moment in...

The study presents an optimal design of simply supported rectangular reinforced concrete beams based on the ultimate limit state philosophy BS8110 and using genetic algorithm as optimization tool. An model was formulated. consists objective function which focuses minimizing steel ratio constraint equations are focused checking that all requirements for satisfied. Results obtained showed a diffe...

Following the Northridge earthquake of 1994, a significant number of steel moment resisting structural systems were damaged. Several studies have been conducted to improve the seismic performance of steel structures and specially their beam-to-column connections. One of the proposed connections for special moment-resisting frames included AISC-358 is Kaiser bolted bracket moment connection, bri...

In order to explore the influence of length and width CFRP as well anchor spacing on reinforcement effectiveness plates concrete beams (RC beams) under secondary load, 7 anchored damaged FRP reinforced are used test beams, 1 unanchored beam is a control beam, structural indicators such ultimate load bending strength analyzed in result. The conclusion that composite plate can effectively prevent...

This paper studies the efficiency of applying an engineered cementitious composite (ECC) layer to tensile surface (RC) beams that were previously strengthened using externally bonded (EB) carbon fiber-reinforced polymer (CFRP) laminates. One control and ten RC produced tested utilizing a four-point loading regime. For beams, two kept only CFRP, additional ECC layers added rest beams. The CFRP w...

Designing protective reinforced concrete (RC) beams against impact loadings is a challenging task. It requires comprehensive understanding of the structural response RC subjected to loads. Significant research efforts have been spent unveil by using analytical models, experimental testing, or numerical investigations. However, these studies used various assumptions in derivations and different ...

Impact force and structural response of reinforced concrete (RC) beams under drop weight impact have been intensively studied reported in the literature. The prediction peak has well investigated while study overall profile governing is limited. parameters acting on a structure including force, plateau duration all affect responses. This investigates profiles from RC beams. effects global stiff...
