Direct Displacement-Based Design; Reinforced Concrete Structures; Equivalent Viscous Damping
Abstract :
[en] It is generally stated that an accurate evaluation of the equivalent viscous damping is a crucial step in the DirectDisplacement-Based Design (DDBD) methodology. A wrong assessment of equivalent viscous dampingcan indeed lead to important errors on the actual ductility demand of the structural elements. The objective of thepresent contribution is to assess and compare different existing formulas for the evaluation of the equivalent damping and to provide information on the impact of choosing one or another formulation on the seismicdesign. It is more precisely focused on the very recent proposals of Dwairi – Kowalsky and Blandon –Priestley.
