RISStress-Strain Curves of Structural and Reinforcing Steels after Exposure to Elevated Temperatures
Publisher: American Society of Civil Engineers
Abstract: For the evaluation of damage to a structure after exposure to fire, the residual mechanical properties of structural materials need to be evaluated first. Many factors can affect the post-fire behavior of structural and ...

Effects of Sustained Load on Concrete-Filled Hollow Structural Steel Columns
Publisher: American Society of Civil Engineers
Abstract: The use of concrete-filled hollow structural steel (HSS) columns has become widespread in the past few decades. However, these members are subject to static long-term behaviors under sustained loading, a common phenomenon ...
Simplified Numerical Modeling of Axially Loaded Circular Concrete-Filled Steel Stub Columns
Publisher: American Society of Civil Engineers
Abstract: Behavior of concrete-filled steel tubular (CFST) columns can be predicted accurately using detailed finite-element (FE) modeling, but such models are tedious to build and impractical for frame analysis. In contrast, ...
Behavior of Concrete-Encased CFST Members under Axial Tension
Publisher: American Society of Civil Engineers
Abstract: This paper studies the behavior of concrete-encased concrete-filled steel tube (CFST) members under axial tension. Experimental results of thirteen specimens were reported. The variables in the test were the diameter of ...
Structural Behavior of SRC Beam-to-Column Joints Subjected to Simulated Fire Including Cooling Phase
Publisher: American Society of Civil Engineers
Abstract: This paper presents the test results of three steel-reinforced concrete (SRC) columns to SRC beam joints under combined loading and fire. Simulated fires, including heating and cooling phases with different heating times, ...
Behavior of Concrete-Encased CFST Members under Axial Tension
Publisher: American Society of Civil Engineers
Abstract: This paper studies the behavior of concrete-encased concrete-filled steel tube (CFST) members under axial tension. Experimental results of thirteen specimens were reported. The variables in the test were the diameter of ...
Performance of Steel-Reinforced Concrete Beam-to-Column Joints after Exposure to Fire
Publisher: American Society of Civil Engineers
Abstract: This paper presents a numerical analysis on the postfire behavior of steel-reinforced concrete (SRC) column to axially and rotationally restrained SRC beam joints. A finite-element analysis (FEA) model was developed to ...
Seismic Performance of Concrete-Encased CFST Piers: Experimental Study
Publisher: American Society of Civil Engineers
Abstract: Concrete-encased concrete-filled steel tube (CFST) box members have been recently used as piers and arches in bridges owing to their high stiffness and strength. However, the seismic behavior of these members has not been ...
Bond Behavior of Concrete-Filled Steel Tubes at Elevated Temperatures
Publisher: American Society of Civil Engineers
Abstract: Extensive studies have been conducted into the bond behavior in concrete-filled steel tubes (CFST) at ambient temperature. However, the bond behavior of CFST columns subjected to fire is still unclear. A total of 24 push-out ...
