In this article, a new approach is presented to solve the double-track railway rescheduling problem, when an incident occurs into one of the block sections of the railway. The approach simultaneously considers three ...

In the present study, the non-metal acoustic waves monitor, TH204 has been used to determine P-wave velocity of compacted expansive soil under the condition of drying-wetting cycles with constant amplitude, to explore the ...

Topographical and mechanical properties of soil layers can lead to amplification or attenuation of seismic waves. Such a phenomena can be theoretically explained by means of ground response analysis. Definition of boundaries ...

Geocell is an effective type of geosynthetics for improving the performance of reinforced soil foundations due to provision of lateral confinement for the infill soil. In this research, in order to study the bearing ...

Dynamic compaction is a useful economic method for improving different soil types, especially loose sandy fills. However, the method has been rarely used in the vicinity of slopes due to stability concerns. In this research, ...

Recently, there has been lots of studies about ductility reduction factor of CBFs, because AISCs seismic design provision has been changed significantly since 2010, So a comprehensive study is needed for seismic designing ...

In geostatistical analysis, spatial interpolation at any unmeasured point is done using the parameters of a variogram model that matches the experimental data. Several variogram models can be used and the accuracy of the ...

In seismic resistant design of moment frames, the structure behavior under earthquakes has to be examined, considering various damage criteria. Damage indices can be estimated by using endurance time (ET) method with minimum ...

Waste tires are extensively being used in civil engineering applications to improve flexibility and elastic properties of the base foundation material. Moreover, by using pure tires or soil-tire mixtures, rubber stockpiles ...

The behavior of SiO2 and metakaolin in aggressive environment when used separately as a supplementary cementitious material was studied for three different replacement levels: 5%, 10% and 15%. SiO2 and metakaolin were used ...

Ski jump is one of the most e ective structures in energy dissipation over spillways. Spillways have long been of practical importance to safety of dams. The major criteria in hydraulic design are based on the analytical ...

Structural engineers have recognized unstiffened Steel Plate Shear Wall (SPSW) as an economical lateral resisting system, due to the post-buckling capacity, energy dissipation and deformability.  This study investigates ...
