This paper reports on part of an ongoing experimental program at The University of Adelaide on the seismic behavior of high-strength concrete (HSC)-filled fiber reinforced polymer (FRP) tubes (HSCFFTs). The results from three square concrete-filled FRP tube (CFFT) columns that were tested under combined constant axial compression and reversed-cyclic lateral loading are : Yunita Idris, Togay Ozbakkaloglu. The volumetric strain determined using Equation (5) was drawn versus the axial compressive strength in Figure 9 for some specimens. Until the concrete reached its unconfined compressive strength under loading, it was in contraction with negligible difference between Rubcrete and conventional by: 1.

The size of the coarse aggregate was 10 mm. Concrete. In recent years, high strength concrete columns have been widely used in many structures, especially, in high-rise buildings. ACI Committee defined high strength concrete as a concrete strength of 41 MPa. More recently, compressive strengths approaching MPa have been used in Cited by: 5.

The strength increase can be as high as 27%. Tension and compression. A pessimum loading case is encountered when a combination of tensile and compressive loads are applied to concrete. The overall strength of concrete is reduced substantially due to the additive effect tensile strains (from Poisson effect and from the tensile principal stress). The aim of study is to understand the behavior of normal and high strength concrete including comparison of empirical formulae proposed for calculation of ultimate strain and strain at peak stress for High Strength unconfined concrete in European design standard EC: with the experimental results and proposal for revision in IS

This paper presents the results of an experimental study on the behavior of FRP-confined normal- and high-strength concrete under axial compression. A total of 24 aramid and carbon FRP-confined concrete cylinders with different concrete strengths and FRP jacket thicknesses were tested under monotonic and cyclic loading.

This paper presents the results of an experimental study on the behavior of FRP-confined normal-and high-strength concrete under axial compression. The implementation of HSC over normal-strength concrete (NSC) in the construction of bridges and multistory buildings offers superior performance and economy.

The majority of the existing studies on the axial compressive behavior of FRP-confined concrete have focused on NSC and only a few studies have been concerned with FRP-confined : Monika Nain, Mohanad M. Abdulazeez, Mohamed A. ElGawady. Behavior of FRP-Confined Normal- and High-Strength Concrete under Cyclic Axial Compression.

An important application of fiber-reinforced polymer (FRP) composites is as a confining material for concrete, both in the seismic retrofit of existing reinforced concrete columns and in the construction of concrete-filled FRP tubes as earthquake-resistant columns in new construction.

Thirty stub columns, including six NSC/HSC, six ECC and 18 ECC-encased NSC/HSC (ECC–NSC/HSC) are tested under axial compression. The effects of ECC strength, ECC encasement thickness, concrete strength and cross-section shapes (circular, square and rectangular) are then investigated and reported in terms of failure modes, strength ratios, post-peak ductility and energy Cited by: 2.

A series of compression tests were conducted on 3 × 6 in (762 × 4 mm) cylindrical specimens using a modified testing method that gave the complete stress–strain behaviour for high-strength concrete with or without tie by: axial compressive strength of steel fibre reinforced normal and high strength concrete square columns.

Due to the military nature of the past research work there is a serious lack of blast tests of concrete structures. With the increasing applications of high strength concrete in the construction industry, the understanding of its behaviour under multiaxial loading is essential for reliable analysis and safe design.

Results from this study provide the means to predict the failure condition for high-strength concrete under combined stresses. The experimental program was comprised of testing high-strength concretes at three different compressive strength levels. The three strength levels included concretes with compressive strengths of 6 ksi (42 MPa), 10 ksi.

The results of axial compression tests of concrete block masonry prisms are reported. The results show that the strengths of grouted prisms are not affected much by the mortar joint.

Science China Technological Sciences 57 (12): Crossref, Google by: 1. Concrete is very weak in tension, the direct tensile strength is only about 7 to 15 percent of its compressive strength.

It is difficult to perform a direct tension test on a concrete specimen, as it requires a purely axial tensile force to be applied, free of any misalignment and secondary stress in the specimen at the grips of the testing machine. This suggests the minimum shear reinforcement equations of the ACI Building Code need to include the effect of axial compression.

Based on a test database of 77 high-strength columns and the biaxial behavior of high-strength concrete, this study proposes concrete shear-strength equations incorporating the weakening effect of axial compression.

The compressive strength of RuC with high rubber contents (replacement volumes >50–60%) can be up to 90% lower than that of normal concrete [12,13,17,18].

Such low strength can be mainly attributed to the a) low stiffnessFile Size: 1MB.
