Summary The behavior of reinforced concrete members subjected to seismic loads is mainly based on the ultimate strength and its ductility. Based this, an additional configuration transverse reinforcement using high‐strength multiple‐tied‐spiral was proposed improve ductility concrete. In this paper, experimental study a number axial loading tests columns confined with described. effects spacing circular spiral rectangular hoop, area were investigated. formulas compressive corresponding...
To improve the mechanical behaviour of reinforced concrete (RC) columns with square cross-section, an additional configuration transverse reinforcement using high-strength multiple-tied spirals is proposed to achieve better lateral confinement and delay or avoid buckling longitudinal bars. In total, 12 specimens are designed for axial compression test, including ten RC multiple-tied-spiral (MTSTR) two conventional stirrups provide a reference. The variables in experiment spacing circular...
The performance of a new type concrete columns reinforced with multi-tied spiral transverse reinforcements called MTSTR has not yet been investigated and compared other types under eccentric loads. In this regard, three columns, concrete-filled steel tube column (CFST), traditional (TCC) were simulated in study by nonlinear finite element (FE) method. comparison between the load–moment interaction (P-M) diagrams these revealed that is weakest among tension-controlled region P-M diagram. An...
An RC shear wall (wall1), a composite composed of single external steel plate connected to concrete panel (wall2), constructed from two plates an internal (wall3) and finally fabricated with embedded within (wall4) are considered in this study their behavior assessed compared under the effect in-plane cyclic load. Variation three functions include load capacity, energy absorption stiffness walls evaluated numerically using ABAQUS finite element software. The performance numerical models is...
<p indent="0mm">The technique of grouted anchor rods with bushings is a new strengthening and repair that can be used for repairing mass brick masonry ancient buildings without damaging their appearance. In order to study the pull-out performance inside historic masonry, tests on 21 fullness mortar joints, anchoring depth, drilling diameter anchorage direction as research parameters were designed completed, failure modes rods, force-slip curves, distribution bar strains well interface...
This research investigates the flexural performance of slabs reinforced with high-strength steel-strand mesh (HSSM) and engineered cementitious composites (ECCs). By employing finite element analysis (FEA) theoretical modeling, this study aims to deepen understanding how these materials behave under bending stresses. A model was developed simulate nonlinear behavior ECCs during bending, considering critical elements such as tensile compressive damage, well bond-slip interactions between...
To better understand the confining effect of multiple-tied-spiral transverse reinforcement (MTSTR) for concrete with rectangular cross-section, eight columns were fabricated and tested under axial compression; four used MTSTR, while remainder counterpart reference reinforced by conventional stirrups. The main variable considered was confinement index reinforcement; this includes ratio interior circular spirals to that exterior hoops sum indices. results showed MTSTR exhibited ductility than...
Summary Most of existing codes ignore the effect arch action on shear strength reinforced concrete (RC) walls, and it leads to more conservative results. A new model considering influence truss RC walls is proposed in this paper. The provided by obtained modified compression field theory, deformation coordination between arch, which has an upper bound value. Experimental data 78 failed are collected evaluate adequacy method comparing with models Hwang Lee, Wood, ACI 318‐11，, EC8, MCBC‐04,...
This article proposes a new connection between steel bearing and reinforced concrete column, which is mainly used for provisionally providing jack support in existing structures. In this suggested joint, the consisted of two or four symmetrical components assembled by high-strength bolts, surrounds column tapered tube balances vertical load via friction force concrete, that is, through self-locking mechanism. The proposed joint can be easily at construction site also disassembled reused many...
