creep effect on the behavior of concrete beams reinforced

PDF) Creep Effects in Plain and Fiber-Reinforced Polymer

Deflections predicted by step-by-step in time model versus experimentally measured deflections for Beam 1 (reinforced with steel only), including effect of concrete creep and tension stiffening of

PDF The Effect of Tension Stiffening on The Behaviour of R/C Beams

tension is assumed to carry zero stress. This tension stiffening effect may be significant in the service load performance of beams and slabs. This phenomenon is also effective in long-term behaviour of concrete members due to the creep and shrinkage of the concrete.

Effect of shrinkage restraint on deflections of reinforced

This paper presents the results of a study aimed at investigating the effects of restrained shrinkage on the in-plane deflection behavior of reinforced beams cast with self-compacting concrete. The load-deflection data from the tests on two sets of heavily-reinforced concrete beams were analyzed. The first set of beams was made with self-compacting concrete while conventionally vibrated

Debonding Failure of CFRP Reinforced Concrete Beams and

Fiber reinforced polymer (FRP) has drawn increasing interest from engineers as an acceptable method of performing civil structure remediations and upgrades. A majority of the applications currently used are for concrete structures. FRP can be used as containment for concrete columns or as shear and/or flexural reinforcement for concrete beams.

Parametric Study of Flexural Strengthening of Concrete

Environmental factors, material aging, and overloading may affect the bearing capacity of reinforced concrete structures (such as beams, columns, slabs, etc.). Compared with demolition and reconstruction, FRP (Fiber Reinforced Polymer) strengthening can reduce costs and optimize investment.

Experimental study on the time dependent flexural behavior

long-term behavior of crack width in PRC beams, especially the effect of creep and drying shrinkage, is not clear. In this paper, cracking, deformation and crack widths of PRC beams under the sustained flexural load will be discussed with the data of creep and drying shrinkage of concrete without reinforcement.

Cracks in Concrete - Building Research

Cracks could be developed at the concrete surfaces mainly due to Shrinkage, Temperature effect, Corrosion of steel rebars and Creep effect in long term. Cracking phenomena aggravate the process of Carbonation & Chloride attack that leads to the corrosion of reinforcement; thereby reducing the durability of structures.

LONG TERM BENDING BEHAVIOR OF ULTRA-HIGH

The behavior of the four beams was analyzed in terms of time-increasing of strains and deflections. In addition, the influence of different quantities of steel-fibers added to the concrete mass was monitored, and their effect on the creep of the compressed zone of the beam
