نویسندگان
چکیده
The behavior of hollow-core columns composed reactive powder concrete (RPC) contained by a circular carbon fiber reinforced polymer (CFRP) tube is investigated numerically in this work. This research used hollow core column samples with an outside diameter 20.6 cm, interior 9cm, and height 80cm. These examples have been created utilizing 116 MPa concrete. Nine groupings specimens were created. A control set nine unconfined stirrups strengthened 12mm longitudinal bars (HCRPC). Groups two through five produced up RPC similar reinforcement but externally confined CFRP 0.131, 0.262, 1.2, 2.4mm thick (These thicknesses are commercially available (0.131 for one layer sheet, 0.262 layers sheet; 1.2 plate. And 2.4 two-layer plate) respectively, placed at mid-length the columns. Sets six to nine, on other hand, identical previous sets, restriction has put both columns' ends. Axial load thru center uniaxial loading 2.5 5 cm eccentricities from applied all According findings, confinement boosted strength HCRPC marginally.

Behaviour of FRP strengthened concrete columns under eccentric compression loading
This paper presents results of testing eccentrically loaded columns externally wrapped with two types of materials. Six cylindrical (205 mm diameter and 925 mm height) plain columns were cast and tested. Half of the columns were wrapped with GFRP and the other half with CFRP. All columns were tested by applying an axial load at 50 mm eccentricity. In each group (GFRP or CFRP wrapped) of columns...
متن کاملBehavior of FRP-Confined Reactive Powder Concrete Columns under Eccentric Loading
Fiber reinforced Polymers (FRP) have widely used for the purposes of enhances strength and ductility of concrete columns. Proper design of such hybrid columns, however, requires a better recognition of the behavior of concrete columns confined with FRP. In this paper, the influence of FRP thickness, concrete compressive strength, and column size on the performance of eccentrically loaded reacti...
متن کاملTime-Dependent Behavior of Reinforced Polymer Concrete Columns under Eccentric Axial Loading
Polymer concretes (PCs) represent a promising alternative to traditional cementitious materials in the field of new construction. In fact, PCs exhibit high compressive strength and ultimate compressive strain values, as well as good chemical resistance. Within the context of these benefits, this paper presents a study on the time-dependent behavior of polymer concrete columns reinforced with di...
