A parametric experimental study has been conducted to investigate the combined effect of silica fume and polypropylene fiber onthe workability and dryingshrinkage of concrete composite containing fly ash. Four contents of ...

In this research, Method of Fundamental Solution (MFS) is coupled with Particle Swarm Optimization (PSO) technique to determine the optimal phreatic line in unconfined seepage problems. To model the unconfined boundary ...

Unsaturated soil shear strength can be determined using effective stress relation that depends on the effective stress parameter. Several models have been developed in past few years to estimate this parameter. In this ...

In this paper, a new technique in weight optimization of pin connected structures is proposed. Using some principles of structural analysis, the concepts of similar trusses in structural analysis and optimum similar trusses ...

Determining the soil shear strength parameters, i. e., cohesion (C), internal friction angle (ϕ)is done by means of laboratory tests and the in situ testing data. The cone penetration test, cone penetrometer test (CPT) is ...

Setting piers is an effective way to overcome the limits of manufacture and operation of the gates for large span culverts or tunnels. However, the piers, if designed improperly, will bring about water-wing to strike the ...

The aim of this study is to determine the relationships of yield-capacity-risk in a multiple reservoir system. In this study, yield, capacity and risk have been defined as the average energy production, storage volume of ...
