Several types of fibers have enhanced the structural response reinforced concrete-filled steel tubes (CFSTs). This article presents a state-of-the-art review studies done on axial compressive behavior and glass fiber-reinforced CFSTs. The aim using is to improve research indicates findings experimental programs analytical evaluations effects fiber incorporation results this work demonstrate tha...
ظهور بتن خودمتراکم (بدون نیاز به ویبره) به عنوان یکی از بتن های نسبتاً جدید، باعث جلب نظر دست اندرکاران صنعت بتن دنیا گردید. استفاده از بتن خودمتراکم علاوه بر مزایای نسبی فراوان اثبات شده، می تواند سرعت ساخت اعضاء بتنی را افزایش دهد و باعث صرفه جویی اقتصادی همراه با افزایش کیفیت گردد. در اعضاء پیش و پس کشیده استفاده از بتن با کیفیت و مقاومت بالا ضروری می باشد، به همین دلیل استفاده از بتن خودمترا...
To improve the seismic behavior of shear walls, a new composite wall composed steel-fiber-reinforced high-strength concrete (SFRHC) web and two square concrete-filled steel tube (CFST) columns, namely with CFST is proposed in this paper. Therefore, main purpose paper to present an experimental investigation SFRHC columns. Pseudo-static tests were carried out on seven performance walls was studi...
Corrosion of reinforcing and prestressing steel due to chloride contamination is one of the primary causes of deterioration of concrete structures. A review of published literatures shows that the research on the deterioration of mechanical properties of reinforcing steel is more than that on prestressing strands, even though the corrosion of prestressing strands may trigger structural collapse...
Non-destructive testing in reinforced concrete (RC) for damage detection is still limited to date. In monitoring the damage in RC, 18 beam specimens with varying water cement ratios and reinforcements were casted and tested using a four-point bending test. Repeated step loads were designed and at each step load acoustic emission (AE) signals were recorded and processed to obtain the acoustic em...
