Abstract: This technical note analyzes the stability of a simple beam subjected to spatially varying random seismic excitations. It uses the stochastic average method to calculate the stability boundaries of a beam under various ...

Abstract: This paper studies the effects of spatial variations of multiple earthquake ground excitations on responses of in‐plane circular incompressible arches. The responses of arches subjected to both correlated horizontal and ...

Abstract: Terrorist bombing and accidental explosion may generate extreme loading conditions on nearby structures, resulting in damage and even collapse of structures. The degree of damage to a structure depends on the capacity of ...

Abstract: Vibration-based methods are being rapidly applied to detect structural damage. The usual approaches incorporate sensitivity analysis and the optimization algorithm to minimize the discrepancies between the measured vibration ...

Abstract: Civil infrastructures are critical to every nation, due to their substantial investment, long service period, and enormous negative impacts after failure. However, they inevitably deteriorate during their service lives. ...

Abstract: Many civil and mechanical engineering structures can be simplified as double-beam systems, i.e., a primary beam and a secondary beam connected to the primary beam. Many studies have investigated the vibration ...

Abstract: Modeling of structural nonlinear dynamic behavior is a central challenge in civil and mechanical engineering communities. The phase space embedding of response time series has been demonstrated to be an efficient coordinate ...

Abstract: This study investigates the impact resistance of fiber-reinforced polymer (FRP) confined concrete. Concrete cylinders were wrapped with carbon FRP (CFRP) or glass FRP (GFRP) with a varied number of layers and wrapping ...

Abstract: Extensive research has been conducted to investigate the blast effects on building structures and the protective design methods using the fiber-reinforced polymer (FRP) strengthening concepts in resisting structural damage ...

Abstract: This study investigates the impact behavior of fiber-reinforced polymer (FRP)-strengthened reinforced concrete (RC) beams and FRP contribution to shear strength. Thirteen RC beams (1,500×150×250  mm) were tested against ...
