High strength steel is widely used in engineering, especially light structures. However, due to the material properties of high steel, its seismic performance has attracted wide attention. To study hysteretic behavior H-shaped members thin-walled sections Q690 a finite element model was built up by using general analysis software ABAQUS. Based on model, an extensive parametric carried out. The ...

Metal thin-walled members have been widely used in building industry. Usually they are utilized as purlins, girts or ceiling beams. Due to slenderness of thin-walled cross-sections these structural members are prone to stability problems (e.g. flexural buckling, lateral torsional buckling). If buckling is not constructionally prevented their resistance is limited by buckling strength. In practi...

Tyre components are high-quality materials, which can be utilised and disposed into construction projects. Despite its high ductility impact resistance, rubberised concrete (RuC) with rubber content has a strength much lower than that of conventional concrete. Previous research shows confinement by jacket material significantly improve the RuC. This paper presents how infilling RuC to cold-form...

Carbon nanotubes (CNTs) are a novel nanomaterial with wide potential applications; however the adverse effects of CNTs following environmental exposure have recently received significant attention. Herein, we explore the systemic toxicity and potential influence of 0-1000 mg L(-1) the multi-walled CNTs on red spinach. The multi-walled CNTs exposed plants exhibited growth inhibition and cell dea...

Public advice columns have provided information, satisfied reader curiosity, and ignited discussion since the late 1600s. The role of the advice columnist can be understood as a form of cultural intermediary who identifies and assesses individual problems of potential relevance to wider audiences. Online columnists are now joined in this analysis of the human condition by communities of contrib...

Clickomania is a classic computer puzzle game (also known as SameGame, Chain-Shot!, and Swell-Foop, among other names). Originally developed by Kuniaki “Morisuke” Moribe under the name Chain-Shot! for the Fujitsu FM-8, and announced in the November 1985 issue of ASCII Monthly magazine, it has since been made available for a variety of digital platforms [Mor03]. Figure 1 shows some examples. Alt...

There have been great developments in the area of civil engineering in the recent few decades and among these, construction and material innovation are quite prominent. Steel-concrete composite construction has emerged as one of the fastest methods of construction. Even though considerable research efforts on conventional reinforced concrete columns have been executed prior to now, concrete fil...

brass ferrules have been used as packing in a laboratory- scale glass distillation column approaching pilot plant size because of their availability in all sizes and low cost. the available size range is such that these ferrules could also be used in industry and the results of this study could be scaled up. the performance of the new packing has been compared with the performance of glass pack...

it introduced an innovative bioengineering method of consolidating incompact sand by urea-hydrolysis producing calcite cementation under the inducement of urease producing microbe. in the paper it discussed the effects of cementation methods and time on porosity and mechanical properties of microbe-inspired cementing sand columns. method a adopted reaction fluid gravitational permeating and ext...
