regarding the importance of the prevention of hazards and adverse environmental impacts in industrial and populated areas such as southern parts of tehran city, the response of impulsive period ground-supported tanks were assessed. having considered the study area's soil properties, the response of ground-supported tanks was modelled. regarding the soil properties of southern parts of tehran, t...

Steam accumulation is one of the most effective ways thermal energy storage (TES) for solar (STE) industry. However, steam accumulator concept penalized by a bad relationship between volume and stored; moreover, its discharge process shows decline in pressure, failing to reach nominal conditions turbine. From economic point view, 60% 70% cost TES that pressure vessel tanks (defined as US$/kWhth...

Article history: Received: 11. 09. 2013. Received in revised form: 01. 10. 2013. Accepted: 15. 10. 2013. Researches into the constitutive relation of the super high strength and high performance concrete and the stress strain relationship of the ultrastrength concrete-filled steel columns are rare. Therefore, this paper based on continuous mechanics presents the relationship of mathematical des...

Within this paper, the assessment of tension stiffening effects on a reinforced concrete element with the circular sections subjected to axial and bending loads is presented. To this purpose, an enhancement of an analytical model already present within the actual technical literature is proposed. The accuracy of the enhanced method is assessed by comparing the experimental results carried out i...

In engineering practice, slots of different shapes and orientations are made with a view to satisfy the functional requirements. The presence of slots increases the complexity of the analysis (by stress concentration) of structural members/elements. Studies have been commonly done on plain concrete slab with rectangular and circular opening, while only few studies have been done on slots of lar...

The use of Glass Fibre Reinforced Polymer (GFRP) bars is considered an alternative option in reinforcing concrete structures instead of conventional steel bars especially in harsh severe environments, due to their mechanical properties and physical characteristics. GFRP bars offer many advantages over steel counterparts such as corrosion resistance, high tensile strength, low weight and electro...
