| It can be learned that the equivalent viscous damping ratio is a crucial parameter in the application of the displacement based (DBD) method. Analytical studies presented here and elsewhere indicate that the equivalent viscous damping ratio is highly dependent on the axial load level. Furthermore, the same can apply for the loading type; namely, seismic and blast loads. Based on research findings, a generalized expression was developed that can be used to design or assess the blast resistance capacity of reinforced concrete members. Furthermore, successful implementation of the DBD method also requires the use of an inelastic shock spectrum to estimate the design displacement. A detailed analytical formulation was used to develop an inelastic shock spectrum for the design of blast resistant structures using the DBD method. |
