Abstract The load scenario with a compressive force applied to an anchored bar (push-in mode) has not been sufficiently addressed so far reference fatigue, since most of the studies available in literature are focused on bond behavior under tensile forces (pull-out mode). However, special structures like towers wind turbines subjected alternating moments (and tensile-compressive forces) due var...

in civil engineering concrete is a material combined of hydraulic cement, sand, gravel and water. gravel and sand compose 60 to 70 percent of concrete. these aggregates support compression force of concrete. cement paste acts as glue to stick grain together. in bushehr factories producing aggregates do not operate according to astm standards, so that fineness modulus (fm) of the produced sands ...

Fiber reinforced polymer (FRP) material is currently being produced in different configurations and widely used to strengthen and retrofit concrete structures and bridges. It is also possible to apply other strengthening methods without changing the appearance or the dimensions of the structure. Near Surface Mounted (NSM) is a recent strengthening method using CFRP bars (rods or laminate strips...

The performance of reactive powder concrete (RPC) is much higher than that ordinary concrete, and the engineering application gradually increasing. bond failure process slip between RPC reinforcement will show new characteristics. It necessary to study behavior steel bar. direct drawing test was carried out on 36 bonding specimens in order bar concrete. research shows cohesive force consists th...

This paper presents the results of an experimental program carried out on slender elliptical hollow section columns filled with concrete. Given the reduced number of experimental results found in the literature on concrete filled tubular columns with elliptical cross-section, the main objective of this paper is to compare the behaviour of such innovative cross-sections under ambient and high te...

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...
