A Simple Approach to Static Analysis of Tall Buildings with a Combined Tube-in-tube and Outrigger-belt Truss System Subjected to Lateral Loading
(Materials and Energy Research Center, 2012-07-01)In this paper, an efficient technique is presented for static analysis of tall buildings with combined tube-in-tube and outrigger-belt truss system while considering shear lag effects. In the process of replacing the ...

Simplified Approach for Torsional Analysis of Non-homogenous Tubes with Non-circular Cross-sections
(Materials and Energy Research Center, 2012-07-01)In this paper a method is presented for torsional analysis of non-homogeneous tubes with arbitrarily shaped cross-sections. A previously presented method based on Bredt’s theory is extended to achieve formulas for torsional ...

Nonlinear Analysis of a Flexible Beam Actuated by a Couple of Active SMA Wire Actuators
(Materials and Energy Research Center, 2012-07-01)There are two different ways of using SMA wires as actuators for shape control of flexible structures; which can be either embedded within the composite laminate or externally attached to the structure. Since the actuator ...

Global Stability for Thermal Convection in a Couple Stress Fluid Saturating a Porous Medium with Temperature-Pressure Dependent Viscosity: Galerkin Method
(Materials and Energy Research Center, 2012-07-01)A global nonlinear stability analysis is performed for a couple-stress fluid layer heated from below saturating a porous medium with temperature-pressure dependent viscosity for different conducting boundary systems. Here, ...

Modeling of Combustion and Carbon Oxides Formation in Direct Injection Diesel Engine
(Materials and Energy Research Center, 2012-07-01)When looking at the effects of diesel engine exhaust on the environment, it is important to first look at the composition of the exhaust gases. Over 99.5% of the exhaust gases are a combination of nitrogen, oxygen, carbon ...

Comparison of Lift and Drag Forces for Some Conical Bodies in Supersonic Flow Using Perturbation Techniques
(Materials and Energy Research Center, 2012-07-01)Numerical methods are not always convergent especially in higher velocities when shock waves are involved. A comparison analysis is performed to study the supersonic flow over conical bodies of three different cross sections ...

Shrinkage Curve: Experimental Study and Modelling
(Materials and Energy Research Center, 2012-07-01)In order to study the shrinkage process of clayey soil, we perform a modified laboratory test allowing to measure simultaneously and continuously the vertical displacement and the weight of natural state specimen. The ...

Determining an Economically Optimal (N,C) Design via Using Loss Functions
(Materials and Energy Research Center, 2012-07-01)In this paper, we introduce a new sampling plan based on the defective proportion of batch. The proposed sampling plan is based on the distribution function of the proportion defective. A continuous loss function is used ...
