Effect of the Concrete Strength on the Concrete-Steel Bond in Concrete Filled Steel Tubes
In this study, the concrete-steel bond strength of concrete filled cylindrical steel tubes has been experimentally investigated. 22 short, high strength and normal concrete filled circular steel tubes were tested. Push-out test was carried out as the common method to evaluate the bond carrying capacity. Four different concrete mixes were used in preparing the specimens. The steel tubes were w...
متن کاملStepwise Regression for shear capacity assessment of steel fiber reinforced concrete beams
The addition of steel fibers into concrete improves the postcracking tensile strength of hardened concrete and hence significantly enhances the shear strength of reinforced concrete reinforced concrete beams. However, developing an accurate model for predicting the shear strength of steel fiber reinforced concrete (SFRC) beams is a challenging task as there are several parameters such as the co...
متن کاملPrediction of axial load capacity of stub circular concrete-filled steel tube using fuzzy logic
a r t i c l e i n f o Keywords: Concrete-filled steel tube (CFST) Confinement effect Fuzzy logic Modified learning from example (MLFE) Axial load capacity A circular concrete-filled steel tube (CFST) has several advantages compared with the conventional reinforced concrete member or hollow steel tube, since the tri-axial state of compression of the concrete infill increases its strength and str...
متن کاملNUREG/CR-6706 "Capacity of Steel and Concrete Containment Vessels with Corrosion Damage" S103109
Corrosion damage has been found in a number of nuclear power plant containment structures, and this could degrade the pressure capacity of the vessel. This has prompted concerns regarding the capacity of corroded containments to withstand accident loadings. For the low-carbon, low-strength steels used in containments, the effect of corrosion on material properties is discussed in this report, a...
متن کاملSeismic Demand and Capacity Evaluation of Rectangular Concrete- Filled Steel Tube (RCFT) Members and Frames
This paper presents analysis tools to be used in quantifying the demand and capacity of composite frames composed of rectangular concrete-filled steel tube (RCFT) columns and steel girders. Worldwide experimental research on RCFT members were consolidated into a database. The experimental results stored in the database were used to quantify the capacity of RCFT members at multiple levels of loa...
