Failure Criterion with Confining Effect on Geogrid-Reinforced Soil and Its Application for Design Method

Effect of Geogrid Aperture Size and Soil Particle Size on Geogrid-Soil Interaction under Pull-Out Loading

Considering the Soil Effects on Design Process of Performance-Based Plastic Design for Reinforced Concrete Structures

In this research, Performance-Based Plastic Design (PBPD) method has been modified according to the proposed method for considering Soil–Structure Interaction (SSI) effects. In the proposed modified method, based on the existing relationships and in order to maintain the simplicity of the PBPD design method, two important parameters have been modified in the PBPD design method. These two parame...

Eccentrically loaded strip foundation on geogrid-reinforced sand

Results are presented for laboratory model tests conducted to determine the ultimate bearing capacity of an eccentrically loaded strip foundation supported by geogridreinforced sand. Only one type of sand at one relative density of compaction and one type of geogrid were used for the tests. The depth of the foundation was varied from zero to B (width of foundation). Based on the laboratory test...

New empirical failure criterion for shale

A new failure criterion was presented to predict the ultimate strength of shale under the triaxial and polyaxial state of stress. A database containing 93 datasets was obtained from the results of the uniaxial, triaxial, polyaxial compressive tests, an indirect tensile test was collected from reliable references, and this test was carried out on the shale samples taken from the southwestern oil...

Investigating the effect of AC overlays, reinforced with Geogrid and modified by sasobit on rehabilitation of Reflective cracking

In this paper, it has been attempted to evaluate the performance of asphalt overlays which were reinforced with geogrid, modified by sasobit and combination of them on rehabilitation of reflective cracking. The laboratory tests under dynamic loading in bending mode were conducted to investigate reflective cracking retardation compared to reference samples. The results illustrated that in a cert...
