The strut-and-tie model (STM) method is useful for the limit state design of reinforced concrete (RC) corbels. However, rational RC corbels, designers must accurately determine strengths struts and nodal zones to check strength conditions a selected STM anchorage reinforcing bars in zones. In this study, authors suggested numerical process determining corbel STMs. technique incorporates two-dim...

The main objective of this study is to evaluate the workability of fresh portland cement concrete while it is still in the mixing truck by determining fundamental rheological parameters (plastic viscosity and yield stress). Nine concrete mixtures with different values of yield stress and plastic viscosity were tested in a concrete truck. The measurements made with the truck were based on the ty...

In this research, an experimental study is conducted to investigate the behavior and strength of high reinforced concrete corbels externally bonded with CFRP fabric sheets Plates different patterns taking into account effect adopted variables in enhancing ultimate strength; shear span effective depth (a/d), configuration, type amount bonding. Eleven were cast tested under vertical loads. Test r...

The study aimed to explore the possibility of strengthening RC corbels with many techniques. research analyzed behavior under a wide range variables. theoretical consisted twelve models reinforced GFRP bars by steel plate. Finite element analysis ANSYS APDL was used verify five specimens. This deals static nonlinear FE simulation investigate Corbels internally and externally. verification exper...

Elevated rail transit has been developed in some big cities in China in recent years. However, specialized codes for design of the bridges in the elevated rail transit system have not yet been established. Based on the prestressed concrete (PC) box girder bridges on Guangzhou metro line 4, some technical features of design principle and technology requisition, ensemble plan and design load of b...

In this paper, five reinforced concrete double-corbel specimens with the same designed bearing capacity are produced according to triangular-truss method (TTM) in GB 50010-2010. Corbels different dimensions and reinforcement configurations obtained by separately varying compressive strength shear span. The differences mechanical performance load-bearing of corbels compared evaluate accuracy rat...

─This paper presents the retrofitting of beam-column joint using CFRP (Carbon Fiber Reinforced Polymer) and steel plate. This specimen was tested until failure up to 1.0% drift. This joint suffered severe damages and diagonal cracks at upper crack at upper column before retrofitted. CFRP were wrapped at corbel, bottom and top of the column. Steel plates with bonding were attached to the two bea...
