Cumulative Plastic Strain

A key aspect of the seismic design of structures is the distribution of the lateral strength, because it governs the distribution of the cumulative plastic strain energy (i.e., the damage) among the stories. The lateral shear strength of a story i is commonly normalized by the upward weight of the building and expressed by a shear force coefficient αi. The cumulative plastic strain energy in a given story i can be normalized by the product of its lateral strength and yield displacement, and expressed by a plastic deformation ratio ηi. The distribution αi/α1 that makes ηi equal in all stories is called the optimum yield-shear force distribution. It constitutes a major aim of design; a second aim is to achieve similar ductility demand in all stories. This paper proposes a new approach for deriving the optimum yield-shear force coefficient distribution of structures without underground stories and equipped with metallic dampers. It is shown, both numerically and experimentally, that structures designed with the proposed distribution fulfil the expected response in terms of both damage distribution and inter-story drift demand. Moreover, a comparison with other distributions described in the literature serves to underscore the advantages of the proposed approach.

The flexural strength of steel fiber reinforced prestressed concrete slab (SFRPCS) with different steel fiber volume ratio (0%, 1%, 2%) is obtained according to four-point bend test, which reveals that the addition of steel fiber can retard the crack growth and enhance the flexural strength of SFRPCS. With the results of fatigue experiment, the damage forms of SFRPCS is analyzed, strain amplitude-cycle ratio curves are obtained and the plastic strain energy of SFRPCS with different steel fiber volume ratio during fatigue process is calculated. It is shown that after 80% fatigue life, the more of the steel fiber volume ratio, the less of the strain amplitude increment, which proves the addition of steel fiber can prevent the concrete matrix from cracking and improve the fatigue performance of SFRPCS, and the plastic strain energy curve of SFRPCS shows obviously three- stage development.
