Abstract The behavior of concrete-filled double-skin poly vinyl chloride (PVC) tubular columns confined by plain PVC sockets is studied in this research. plastic pipes have been used with concrete as columns. has several advantages it inexpensive, light weight for construction, and decrease the time taken construction. Thus can be an alternative to metal various applications which maintenance c...

In the design of reinforced concrete structures several limit states are usually verified using simplified methods instead complex direct calculation. Span-to-depth ratio limits applied for deflection control. same way, a redistribution factor and relative depth compression zone required ductility, but this is not enough. fact, specific span-to-depth limits, which developed in paper, should als...

this study proposes a new linear approximation for solving the dynamic response equations of a rocking rigid block. linearization assumptions which have already been used by hounser and other researchers cannot be valid for all rocking blocks with various slenderness ratios and dimensions; hence, developing new methods which can result in better approximation of governing equations while keepin...

As a new member of concrete-filled steel tube (CFT) structural families, elliptical tubes (CFETs) have great potential to be used as piers and columns in bridges airport terminals because its low flow resistance coefficient reasonable distribution major–minor axis. Hence, the main objective this paper presents an experimental investigation on seismic behavior terminal stirrup-confined (TS-CFET)...

2D actuator composite structures are fabricated of lead zirconate titanate (PZT) and Al2O3 building blocks with an epoxy resin matrix. This novel modular concept gives the possibility to create complex geometric where structure itself tailors physical properties. To improve possibilities excitation or loading determine influence parameters as slenderness ratio t2 · g−1 active area Aactive finit...

Over the last 50 years, research has mainly focused on characterizing In-Plane behaviour of unreinforced masonry infill walls. Recently, focus been addressed to understanding Out-of-Plane behaviour, also from experimental point view. However, in campaigns, there is high variability geometrical and mechanical properties URM walls application loads. Therefore, it important outline critically eval...

The test results on the performance of carbon fiber-reinforced polymer (CFRP)-confined reinforced concrete (RC) columns under axial compression load are presented in this study. Twelve slender CFRP-confined circular RC with a diameter 200 mm were divided into two groups. Six specimens different slenderness ratios 12, 20, 32, 40, 48, and 56 contained each group. experimental demonstrated circumf...

Concrete is one of the main building materials in Peru and worldwide, study its mechanical properties concrete mix elaboration have been extensively developed over time. In last years, new ways with different searched, order to improve properties, including fiber reinforced concrete. The strain-stress under monotonic load objective this investigation, based on experimental tests performed 90 sa...
