Evaluating Overall Ductility Factor of Steel Frames with Viscoelastic Bracing System

Journal of Engineering Science and Technology Review, 2016
The primary aim of this study is to evaluate the overall ductility factor of ordinary moment steel frames with viscoelastic bracing system. Similar frames without viscoelastic bracing assessed and compared as well. Linear history analysis of two types with different number of stories and spans lengths is carried out using different earthquake records ...

Effect of Structural Characteristics Distribution on Strength Demand and Ductility Reduction Factor of MDOF Systems Considering Soil-Structure Interaction

Earthquake Engineering and Engineering Vibration, 2012
It is known that structural stiffness and strength distributions have an important role in the seismic response of buildings. The effect of using different code-specified lateral load patterns on the seismic performance of fixed-base buildings has been ...

Strength–ductility synergy in Mg-Gd-Y-Zr alloys via texture engineering in bi-directional forging

Journal of Magnesium and Alloys
In this work, we successfully fabricate an ultra-high strength Mg-11Gd-3Y-0.5Zr alloy with ultimate tensile strength of 523 MPa and enhanced ductility via cost-effective bi-directional forging (BDF) and subsequent annealing heat treatments.

Evaluation of response reduction factor and ductility factorfor RC braced frame [PDF]

Journal of Materials and Engineering Structures, 2015
Response reduction factor is the factor by which the actual base shear force should be reduced, to obtain the design lateral force during design basic earthquake (DBE) shaking. The response reduction factor (R) is basically depends on Over strength (Rs),
