Abstract: This paper presents an experimental study of the behavior of large‐scale high‐strength concrete columns confined by rectangular ties under concentric loading. Effects of key variables such as the concrete compressive ...

Abstract: This paper presents new equations for the design of confinement reinforcement for ductile earthquake-resistant rectangular and circular columns based on performance measured in terms of curvature demand. These equations ...

Abstract: One disadvantage of most available stress–strain models for concrete confined with fiber-reinforced polymer (FRP) composites is that they do not take into consideration the interaction between the internal lateral steel ...

Abstract: This paper presents a new confinement model based on strain compatibility and transverse force equilibrium. This new approach is capable of predicting the effectiveness of transverse reinforcement, which is key in modeling ...

Abstract: This paper presents a sensitivity-based damage identification of a three-dimensional truss tower tested in the laboratory. A finite-element model is updated by modal parameters obtained from ambient vibration measurements. ...

Abstract: A stress-strain model for confined high-strength concrete has been developed and calibrated against the test results from 50 large-scale high-strength concrete tied columns tested under concentric loading. The effects of ...

Abstract: AbstractReinforced concrete shear walls (RCSWs) constitute the primary seismic force-resisting system for mid-rise and high-rise buildings in western North America. Numerical analysis has indicated that large-magnitude, ...

Abstract: This paper presents relatively simple, analytically derived curves to model the axial and the lateral stress-strain relations of circular concrete columns. The analytical curves describe the full elastoplastic behavior of ...

Abstract: Reinforced concrete columns usually have a minimum amount of transverse steel reinforcement this transverse reinforcement can have non negligible effects on the response of columns retrofitted with fiber-reinforced polymers ...

Abstract: Specialized computer‐aided education tools are necessary to provide a transition between theoretical formulations of matrix methods of structural dynamic computations and the fully automated analysis procedures found in ...
