New Approach for Simulating Reinforced Concrete Walls in Quasi-static Loading

Shear and Flexural Stiffnesses of Reinforced Concrete Shear Walls Subjected to Cyclic Loading

Seismic analyses of concrete structures under maximum-considered earthquakes require the use of reduced stiffness accounting for cracks and degraded materials. Structural walls, different to other flexural dominated components, are sensitive to both shear and flexural stiffness degradations. Adoption of the gross shear stiffness for walls in seismic analysis prevails particularly for the design...

Quasi Distributed OTDR Crack Sensor for Reinforced Concrete Structures

A quasi-distributed fiber optic sensor is developed for embedment in concrete structures. The sensor principles are simple, and therefore, practical for crack detection and deformation measurement in civil structural applications. The distributed sensor developed herein operates based on the intensity measurements of optical power. The sensor consists of a number of individual segments on one l...

Simulation of Nonlinear Seismic Response of Reinforced Concrete Structural Walls

In this study the performance of three macro-models in predicting the nonlinear response of different walls is investigated. The macro-models used are: Equivalent Beam Model, Multiple Vertical Line Element Model and a shear panel model developed by Massone et al. (2006). The walls are classified as slender, intermediate, and squat walls according to their shear-span ratio. First, three single w...
