Nonlinear Analysis of Reinforced‐Concrete Shells
Publisher: American Society of Civil Engineers
Abstract: Nonlinear finite element procedures are presented for the analysis of reinforced‐concrete shell structures. Cracked concrete is treated as an orthotropic material using a smeared rotating crack approach. The constitutive ...
Effect of Surface Cracks on Rayleigh Wave Propagation: An Experimental Study
Publisher: American Society of Civil Engineers
Abstract: This experimental study investigates the use of Rayleigh waves for crack detection in structural elements. Receiver arrays measure surface accelerations at various locations with respect to a vertical slot cut into a thin ...
