The van Genuchten Model (1980) is widely-used for the description of the Soil-Water Characteristic Curve (SWCC) of a variety of soils. This study uses the Genetic Programming (GP) for the presentation of equations estimating ...

Many soil slopes are unsaturated and failure of them can be a major cause of damage to structures. Apart from soil properties, the Soil-Water Characteristic Curve (SWCC) is the backbone of any unsaturated slope analysis. ...

Improvement of sands is frequently carried out by cement together with several other additives. The common additives have high manufacturing costs and negative environmental impacts during their manufacturing process and ...

This paper presents the test results of a proposed ductile moment-resisting beam-column connection for precast concrete frames and a developed3D nonlinear finite element model of this connection in several different details ...

In this paper, the correlation between shear wave velocity and some of the index parameters of soils including standard penetration test blow counts (SPT), fine-content (FC), soil moisture (W), liquid limit (LL) and depth ...

In this paper, a Collocated Mixed Discrete Least Squares Meshfree (MDLSM) method is proposed and used for efficient solution of engineering problems.  Background mesh is not required in the MDLSM method; hence the method ...

In this paper, responses of reinforced concrete core-wall structures connected to the outside columns by buckling-restrained brace (BRB) outriggers in tall buildings were investigated. These buildings are subjected to ...

Statistics upon injured and killed pedestrian accidents in recent years expresses a high vulnerability of this group of road users. By identifying influential factors on the interactions of pedestrians-vehicles and ...

Laboratory experiments were carried out in order to study the influence of the bed roughness on secondary circulations and lateral flow variability in a straight open channel. Flow field and bed shear stress were measured ...

The railroad blocking problem emerges as an important issue at the tactical level of planning in freight rail transportation. This problem consists of determining the optimal paths for freight cars in a rail network. Often, ...

Once a dam fails, large amount of water at rest in the reservoir releases to downstream river and can cause extensive inundation areas, damage to properties, and loss of lives. The outflow hydrograph influences from variety ...

In this study, the lateral buckling of pipelines on a rigid seabed under temperature and internal pressure is discussed regardless of the effects of waves and currents. The analytical results in some cases are compared ...
