The upper bound solution of the factor of safety is obtained by optimization calculation. To evaluate the feasibility of the method proposed in this paper, it was compared with the safety factor calculated by the marginal ...

So far, many studies have been done on the performance of conventional chemical stabilizers such as cement, lime, fly ash or other chemical additives. However, very limited researches were conducted on the mechanical ...

The Iranian Standard of Seismic Design of Structures No. 2800, IBC 2018, ASCE 7-16 and AISC 341-16 suggest that a response factor, R (also referred to as the R-factor), should be used as a measure to account for some ...

This research aims to develop seismic fragility curves for small- and medium-sized concrete bridges. Fragility curves were generated as a function of the probability of reaching or exceeding a specific limit state in terms ...

Existing under-designed structures, which have been built due to the past insufficient constructional knowledge, are an important issue and anticipation of their dynamic responses to seismic events may be a cumbersome task. ...

Innovative Precast Post-Tensioned Concrete Shear Wall (PPCSW) comprises two columns as boundary elements and a main precast shear wall. Although, there have been some researches about the cyclic behavior of the PPCSWs, the ...
