This article presents a novel strategy for structural topology optimization considering damage. In engineering practice, structures are typically designed to have certain load-bearing capacity, with minimal material volume or cost. We aim optimize the of structure weight while guaranteeing predefined load softening behavior quasi-brittle materials. Two different strategies presented: fully nonl...

Different authors conducted studies on fiber reinforced concretes (FRC) with carbon fibres of different lengths and some results showed that concrete mix homogeneously distributed short in their volume have good strength ultra-strain compared to normal plain mix. However, this study is focused more 3-dimensional (3D) fibre plastic (epoxy) CFRP composite thin rods frame used as a reinforcement w...

This research presents the geotechnical zoning map of district 1 in Shiraz municipality with focus on allowable bearing capacity of foundation based on data from 160 boreholes. For this purpose, the mechanical properties are determined according to the results of direct shear, uniaxial, and SPT tests and then safe bearing capacity for strip foundations with widths of 1, 1.5, 2, and 2.5 m, and f...
