existence of cracks in industrial structures is one of the important causes of their failure, especially when they are subjected to important axial compressive forces that might lead to buckling. therefore, it must be considered in stress analysis and designing and loading of such structures. in this paper, the buckling and post-buckling behaviors of stainless-steel cracked plates under axial c...

Abstract:   Previous research on bracing members show that the ductility of bracing members is compromised due to the buckling phenomena. Therefore, many researchers have tried to use special considerations to increase the fracture life of bracing members. Some of these recommendations such as increasing the slenderness ratio, using lower width to thickness ratio, increasing the out-of-p...

This paper introduces a very simple way to evaluate low stress shearing properties of woven fabrics with the advantages of simplicity and easy accessibility. A 200-gram load is applied on small portion of the sample instead of applying the load overall width of the fabric. As a result, buckling of the fabric will happen and the loading-unloading curve will show the behavior of the fabric during...

Application of high strength steel (HSS – S420 and higher grades) is growing nowadays in the civil engineering praxis due to numerous advantages compared normal (NSS S235-S355). The accurate consideration flexural buckling resistance HSS structures highly important design. Higher yield indicates applicability smaller cross-sections, which might be more sensitive for stability problems. purpose ...

The local buckling behavior of vertically aligned carbon nanotubes (VACNTs) has been investigated and interpreted in the view of a collective nanotube response by taking van der Waals interactions into account. To the best of our knowledge, this is the first report on the case of collective VACNT behavior regarding van der Waals force among nanotubes as a lateral support effect during the buckl...

Structural buckling failure due to high external hydrostatic pressure is a major consideration in designing rings and long cylindrical shell-type structures. This paper presents a direct approach for enhancing buckling stability limits of thin-walled rings/long cylinders that are fabricated from multiangle fibrous laminated composite lay-ups. The mathematical formulation employs the classical l...

In this paper, the flexural behavior of High-performance Fiber-Reinforced Cementitious Composite (HPFRCC) has been investigated, especially focusing on the localization of cracks, which significantly governs the flexural behavior of HPFRCC members. From four points bending tests with HPFRCC members, it was observed that almost evenly distributed cracks formed gradually, followed by a localized ...

concentric bracing is one of the most common lateral load resistant systems in building frames, and areapplied to many structures due to their manufacturing simplicity and economics. an important deficiency in thebracing members is their irregular hysteretic loops under cyclic loading. in order to overcome this problem, it isadvised to restrain braces against buckling under compression, since b...
