Application of Shape Memory Alloys in Seismic Isolation: A Review
(University of Tehran, 2014-12-01)In the last two decades, there has been an increasing interest in structural engineering control methods. Shape memory alloys and seismic isolation systems are examples of passive control systems that use of any one alone, ...

Assessment of South Pars Gas Field Subsidence Due To Gas Withdrawal
(University of Tehran, 2014-12-01)Withdrawal of oil and gas from reservoirs causes a decrease in pore pressure and an increase in effective stress which results to a reservoir compaction. Reservoir compaction will result in surface subsidence through the ...

The Effect of Spatial Variability and Anisotropy of Soils on Bearing Capacity of Shallow Foundations
(University of Tehran, 2014-12-01)Naturally occurred soil deposits inherit heterogeneity and anisotropy in their strength properties. The main purpose of this paper is to model the soil stratum with anisotropy consideration and spatially varying undrained ...

Hybrid Fiber Reinforced Concrete Containing Pumice and Metakaolin
(University of Tehran, 2014-12-01)Fiber reinforced concrete (FRC) has been widely used due to its advantages over plain concrete such as high energy absorption, post cracking behaviour, flexural and impact strength and arresting shrinkage cracks. But there ...

Mathematical Modeling of Column-Base Connections under Monotonic Loading
(University of Tehran, 2014-12-01)Some considerable damage to steel structures during the Hyogo-ken Nanbu Earthquake occurred. Among them, many exposed-type column bases failed in several consistent patterns, such as brittle base plate fracture, excessive ...

A Simple Algorithm for Analyzing a Piled Raft by Considering Stress Distribution
(University of Tehran, 2014-12-01)Numerous techniques have been presented by different researchers to analyze piled raft. In order to analyze pile foundation, soil can be modeled as spring, continuous medium, or porous media. Pile can also be modeled as ...
