This paper is concerned about the lateral load response and associated working mechanism of a precast reinforced concrete shear wall involving horizontal connections. An assembling method proposed using dry connection through steel connector (H‐connector) high strength bolts. To investigate effectiveness such an method, two identical wall‐connector assembly specimens have been constructed tested under monotonic loading cyclic loading, respectively, while subjected to constant vertical...
In order to investigate the influence of various factors on working performance, mechanical properties and durability sustainable Reactive Powder Concrete (RPC), make it convenient for choose more cost-effective RPC incorporating industrial byproducts. The effective parameters (water-binder ratio, contents water reducer, replacement ratios fly ash (FA), silica fume (SF) slag powder (SL)) RPCs were examined by tests paste fluidity, compressive flexural strength as well absorption. Besides,...
This paper evaluates the influence of mineral admixtures partially replacing cement, sea sand quartz, water fresh on ultra-high performance concrete (UHPC). The fluidity and mechanical properties were studied. Besides, impermeability, chloride resistance freeze-thaw investigated. Failure modes, scanning electron microscope (SEM) analysis, mass loss, relative dynamic modulus elasticity UHPCs after cycles conducted. results showed UHPC paste gradually increases with improvement water-binder...
This article is concerned about precast reinforced concrete shear walls and the methods of assembling wall panels to form a reliable load transfer system. An method proposed using dry connection through an H-shaped steel connector (H-connector) high-strength bolts. A preliminary design, including H-connector design bolt has been carried out based on force analysis vertical in assembly. On basis finite element verified by experimental study, confirmed monolithic coefficient ( ζ) used evaluate...
Summary This paper presents an experimental study of H‐shaped precast reinforced concrete shear walls involving vertical connections under combined and lateral loading. The H‐wall is composed two prefabricated flange wall panels: one web panel bolted steel between the panels. assembling completely dry without any in situ casting. Three specimens were constructed tested to investigate mechanical behavior seismic performance them. load‐bearing capacity, ductility, energy dissipation,...
An assembling method of precast shear walls was previously proposed using steel–concrete composite bolted connectors. To further investigate the effectiveness and mechanical behavior connector, 11 specimens were fabricated tested under monotonic tensile loading. The test results provided comprehensive data (e.g. load, deformation, failure mode) on effects variation in thickness steel cap plate, concrete strength, bolt tension, diameter. Two typical modes observed test: bearing failure....
In order to promote the utilization of high strength materials and application prefabricated structures, flexural behaviour section steel-precast UHPC (Ultra-High performance concrete) slab composite beams with bolt shear connectors are numerically simulated by finite element (FE) software ABAQUS. The model is verified three steel-concrete tested. Numerical analysis results in good accordance experimental results. Furthermore, parametric studies conducted investigate effects steel concrete...
Precast Concrete (PC) shear walls are becoming popular in building structures. With “wet” connection techniques, PC often behave like conventional cast-in-place walls, where hardening occurs after yielding. In this study, two assembled by the “dry” technique, and one wall, were tested means of quasi-static cyclic loading. The main purpose experiment was to systematically investigate response with varying types vertical form a friction-bearing device. results showed that bearing devices,...
ABSTRACT Considering the continuous development of sustainable development, energy saving, and emission reduction concepts, it is very important to reduce concrete’s cement content in order improve its environmental impact. Using a reactive admixture replace part ultra-high-performance concrete (UHPC) can effectively overall performance carbon dioxide emissions, which an aspect protection. Here, industrial waste residue (fly ash slag), sea sand (SS), manufactured (MS) were used produce UHPC...
