Probabilistic Seismic Hazard Assessment (PSHA) evaluates the probability of exceedance a given earthquake intensity threshold like Peak Ground Acceleration, at target site for exposure time. The stochasticity occurrence seismic events is modelled by stochastic processes and propagation wave in soil typically evaluated empirical relationships called Motion Prediction Equations. large uncertainty...

One of the principle issues concerning practical application steel fiber reinforced concrete (SFRC) is uncertainty related to its structural behavior, primarily caused by partially random distribution and orientation fibers in SFRC elements. This paper aims provide a better understanding how variance material properties affects flexural behavior beams. First, distributed plasticity finite eleme...

seasonal variations of climatic parameters are significant in arid and semi-arid regions and sensitivity of each parameter may differ in different seasons. no work has been done in this regard in iran. therefore, in this study, sensitivity analysis of the asce-penman-monteith grass reference evapotranspiration (eto) equation was investigated on the basis of variation of mean air temperature (tm...

this paper presents an economic evaluation of gas to liquids (gtl) project using “south-pars” gas field of iran based on the latest actual performing gtl projects. iran has the world’s largest reserves of natural gas and can satisfy the projected long-term market demand of gtl products which have lower pollution and higher quality than refinery products. the results of cost-benefit analysis sho...
