Optimal Viscous Damper Placement for Elastic-Plastic MDOF Structures Under Critical Double Impulse

Frontiers in Built Environment, 2019
A new method for optimal viscous damper placement is proposed for elastic-plastic multi-degree-of-freedom (MDOF) structures subjected to the critical double impulse as a representative of near-fault ground motions.

Study on fracture parameter calibration and failure characteristics of rock with hole and crack

Deep Underground Science and Engineering, EarlyView.
The SIF and plastic zone equations for a single hole and crack have been derived. The model's failure state leads to the identification of four types of cracks. The plastic zone increases with increased brittleness and decreased crack length. Abstract Cracks within the surrounding rock of roadways significantly affect their stability and failure ...

Assessment of buildings response to earthquakes [PDF]

WIT Transactions on The Built Environment, 2009
Modern buildings are designed to withstand earthquake loads and to reduce the probability of a disastrous collapse or life-threatening damage due to strong earthquakes. Under medium-intensity earthquakes, the damage to buildings should be repairable, and no building damage or discomfort to the occupants should occur due to minor earthquakes.
