Soils have an anisotropic response and changing the inclination (α) and magnitude of the major principal stress will affect the collapse potential and brittleness as well as the shear strength and shear stiffness. In this ...

Not only should dams be evaluated for seismic shaking, but their capability to survive potential fault displacements in their foundations should also be assessed. Safety reviews of existing dams suggest the geological-seismic ...

In this study, a new hybrid method based on Firefly Algorithm (FA) and Harmony Search (HS) techniques, is presented for solving the least-cost design problem of water distribution systems (WDS). This algorithm is designed ...

Silica fume as new supplementary cements have several effects on initial mechanical characteristics and long term improvement. In this paper, the impact resistance and mechanical properties of concrete mixed with silica ...

Determination of site liquefaction potential and taking deterrent action can prevent a significant damage to structures. In this way, a probabilistic liquefaction assessment can develop potential flexibility and risk ...

Discrete Least Squares Meshless (DLSM) method has been used for the solution of different problems ranging from solid to fluid mechanics problems. In DLSM method the locations of discretizationpoints are random. Therefore, ...

Application of an elastoplastic-viscoplastic constitutive model for tunnel safety evaluation is presented in this paper. For achieving this purpose, in the first step, through FLAC code, the model parameters were identified ...

Ward’s, hierarchical clustering method, is applied to classify the annual floods and identify the hydrologic homogeneous regions in Turkey. For this aim, the annual flood data obtained at the 117 gauging stations having ...

Sluice gates are widely used for flow control in open channels. Flow under a gate is complicated with a rapidly varying free surface and dynamic pressure distribution. Due to this complexity most of the studies to date are ...

Considering the need to invest on road safety programs, an efficiency analysis on the implemented countermeasures is required. The system presented in this study is designed to evaluate the efficiency related to the measures ...

In this paper, the dynamic characteristics of skewed bridges are explored analytically. Closed form solutions for translational and torsional periods of free vibration and mode shapes are given for slab-girder skewed ...
