A meshfree method for nonlinear analysis of two-dimensional reinforced concrete structures subjected to monotonic static loading is presented. The concrete model is implemented in the context of the smeared rotating crack approach. The stress-strain relationship for steel bars accounts for the surrounding concrete bonded to the bar (tension stiffening effect). The principle of virtual work (var...

Provision of reliability of structures is an important issue at the designing stage. One of reliability aspects is durability. In order to estimate the durability of reinforced concrete it is required to apply standard procedure of calculation which, according to SNIP Regulations 2.03.11-85 Protection of Engineering Structures against Corrosion, can be implemented with the use of means of prima...

An investigation was performed by using carbon fiber-reinforced polymer (CFRP) as the anode material in the impressed current cathodic protection (ICCP) system of steel reinforced concrete structures. The service life and performance of CFRP were investigated in simulated ICCP systems with various configurations. Constant current densities were maintained during the tests. No significant degrad...

This paper investigates experimentally and analytically the torsion behavior of steel fibered high strength self compacting concrete beams reinforced by GFRP bars. Steel fibered high strength self compacting concrete (SFHSSCC) and GFRP bars became in the recent decades a very important materials in the structural engineering field. The use of GFRP bars to replace steel bars has emerged as one o...

As the life age of the existing structures are required to meet the changing demands on civil infrastructures. So strengthening and retrofitting are required. Recently many techniques to strengthen the reinforced concrete beams in flexural by using fiber reinforced polymer (FRP) had appeared. The most famous technique among them is strengthening the (RC) beams with externally bonded FRP sheet t...

an experimental study is conducted on three ½ scales, single-story, single-bay, frame specimens. the first specimen was a reinforced concrete frame with solid-brick infill. the second specimen was a reinforced concrete frame with hollow clay perforated-brick infill. the last specimen was a reinforced concrete frame without any infill. these three specimens were tested by pseudostatic method. di...

concrete beams reinforced with glass fiber reinforced polymer (gfrp) bars exhibit large deflections and crack widths as compared with steel reinforced concrete beams due to the low modulus of elasticity of gfrp bars. different studies show that aci 318 equation for the effective moment of inertia ie does not predict deflection well for frp reinforced concrete beams. the purpose of this paper is...

This report describes a non-linear method of analysis for prestressed concrete structures which predicts behaviour at all stages of loading, from the initial application of prestress up to and beyond the collapse condition. The method uses a segmental line element approach and is a modification of an existing method previously developed for reinforced concrete structures. Comparisons with the r...

7 Corrosion of reinforcing steel in concrete can alter the interface between the steel and concrete and 8 thus affects the bond mechanism. This subsequently influences the behaviour of reinforced 9 concrete structures in terms of their safety and serviceability. The present paper attempts to 10 develop a numerical method that can simulate the behaviour of reinforced concrete walls subjected 11 ...
