Load carrying capacity of flat double-layer space structures majorly depends on the structures' imperfections. Imperfections in initial curvature, length, and residual stress of members are all innately random and can ...

Polymer modified concrete (PMC) consists of Portland cement concrete with a polymer modifier. Its advantages are proper bonding strength to substrate concrete, high tensile and flexural strength and low amount of shrinkage ...

One of the efficient techniques to improve the behavior of the paved road under traffic loads is implementing the geosynthetic material in the sub-base or the soil under the road. In the past years, many researches have ...

In this paper, the initiation and propagation of structural damage in a building due to the truck collision to one of its corner columns were investigated. For this purpose, a three-dimensional 4-story moment resisting ...

One of a feasible and efficient method to retrofit structures is spraying shotcrete which is widely applied around the world. Shotcrete is concrete with fine aggregates which are sprayed through a hose and by air pressure ...

Asphalt modification/reinforcement has received considerable attention as viable solutions to enhance flexible pavement performance. This is mainly prompted by the unsatisfactory performance of traditional road materials ...

In this study, the effect of deep excavation on the seismic response of RC moment resisting building systems has been studied. Deep excavation can cause significant changes in the stress and strain levels of soil environment ...
