dual systems of steel moment frame and reinforced concrete shear wall have combined the advantages of steel frames and reinforced concrete shear wall. these walls have increased the lateral stiffness of steel frames and have reduced seismic demands on steel frames thus providing opportunities to use such system. in this research intermediate dual system of steel moment frame was chosen with int...

abstract   introduction: balance is one of the most important contexts in ageing. improving balance in middle age can prevent falling down in elderly which impose the financial and mental costs to society. imbalance between dominant and non-dominant leg can lead to some problems. that’s way; studying effects of similar exercise on dominant and non-dominant legs of body can prevent problems caus...

The behavior of reinforced concrete with large strain under dynamic loading is non-linear. The non-linear modeling of the reality exactly is much difficult due to a lot of boundary conditions and limited resources. However, the engineering requirement of solutions is somehow relaxed. i.e. it only needs to be within certain limits of errors. This paper presents the interpretation of the structur...

Displacement finite element models of various beam theories have been developed traditionally using conventional finite element basis functions (i.e., cubic Hermite, equi-spaced Lagrange interpolation functions, or spectral/hp Legendre functions). Various finite element models of beams differ from each other in the choice of the interpolation functions used for the transverse deflection w, tota...

Article history: Received: 18.09.2013. Received in revised form: 21.03.2014. Accepted: 24.03.2014. Static structural analysis of a pipe during laying is usually performed by use of finite element analysis tools specialized for this purpose. In this paper, Abaqus/CAE, which is general purpose FEA software, was used for a static non-linear structural analysis of a pipe during pipe laying. The pip...

The purpose of this research is to study the mechanical behavior of a micropump with clamped circular diaphragm which is the main component of drug delivery systems. In this paper, the non-linear governing equations of the circular microplate using Kirchhoff thin plate theory was been extracted based on the modified couple stress (MCST) and classical (CT) theories. Then, the non-linear equation...

In this paper, we examine numerical efficiency of selected Object-Oriented numerical libraries which can be obtained freely on the internet and are open source. This work was largely based on the interesting results reported by the BTL(Benchmark for Templated Libraries) framework on serial numeric linear algebra libraries.

The polyhedra abstract domain is one of the most powerful and commonly used numerical abstract domains in the field of static program analysis based on abstract interpretation. In this paper, we present an implementation of the polyhedra domain using floating-point arithmetic without sacrificing soundness. Floating-point arithmetic allows a compact memory representation and an efficient impleme...
