In this paper, the stability characteristics of single-walled carbon nanotubes (SWCNTs) under the action of axial load are investigated. To this end, a nonlocal Flügge shell model is developed to accommodate the small length scale effects. The analytical Rayleigh-Ritz method with beam functions is applied to the variational statement derived from the Flügge-type buckling equations. Molecular dy...

This paper presents the results of an experimental study on behavior cold- formed steel shear wall panel (CFSSWP) with fibrocement panels as sheathing, when it is subjected in-plane deformations and flexural deformation under perpendicular monotonically increasing horizontal loads longest plane. A full-scale housing section was built three walls a ceiling using commonly used construction detail...

Recently, there has been a resurgence in the adoption of lightweight cold-formed steel (CFS) profiles as structural elements low- to mid-rise modular construction. Typically, openings for doors and windows are ever-present front rear elevations where shear walls find their optimal position ensure lateral stability CFS structures. These architectural design features translate into reduced areas ...

Masonry walls exhibit low tensile strength and high material heterogeneity, which makes them especially vulnerable against cyclic loading conditions, such as those typical in earthquakes. This paper presents the experimental results obtained from tests on three masonry reinforced with textile mortar (TRM) materials subjected to in-plane loading. These full-scale were tested LARGE laboratory at ...

steel structures are usually built with some defects. according to the standard building codes, the central axes of the bracing members should go through the beam-column joints, however, in most of the braced steel structures, bracing members are unintentionally connected eccentrically. this paper presents a numerical investigation on performance analysis of cbfs (concentrically braced frames) ...

in the present paper, an exact solution for transient response of an infinitely long functionally graded thick-walled cylinder subjected to dynamic pressures at the boundary surfaces is presented for arbitrary initial conditions. the cylinder is assumed to have a plane-strain condition and the dynamic pressures are assumed to be imposed uniformly and axisymmetrically on the boundary surfaces. m...

The advancement in steel fabrication technology extends the structural and constructional advantages of cellular beams into arched structure members. However, less attention is given to understanding in-plane out-of-plane behavior performance beams. This article presents a numerical study using finite element package ABAQUS investigate effect arch axis geometry (circular parabolic) impact end s...

Infilled walls are the major non-structural elements which have significant effects on the seismic behavior of structures. The shape and strength of the brick elements are the main parameters affect the strength of the walls. In addition existence of openings may have a reduction effect. To increase the strength of the wall and to improve its behavior, the borders of the openings may be strengt...
