To investigate the mechanical properties of eccentrically loaded steel reinforced recycled concrete filled square tube columns, 14 specimens columns were designed and tested. The failure modes, load-displacement curves, bearing capacity deformation obtained analyzed in detail. In addition, numerical model considering unfavorable effects coarse aggregate (RCA) restraint effect also established b...

Physical and mechanical properties were evaluated for bamboo-oriented strand boards (BOSB) prepared with combinations of two contrasting bamboo species bonded phenol formaldehyde resin under various compression ratios. The strands from the culms Gigantochloa pseudoarundinacea Dendrocalamus asper steam-treated at a temperature 126 °C pressure 0.14 MPa 1 h then washed 1% NaOH solution. Three-laye...

Employing non-metallic reinforcement made of fiber-reinforced polymers (FRPs) as textile grids is one promising extension the utilization range FRP in concrete construction, and thin planar elements reinforced this manner have high application potential bridge or parking garage decks, façades, webs flanges hollow core cross-sections. Existing models for predicting shear resistance such were der...

The aim of this study was to evaluate the quality patterns Switenia macrophylla, Cedrelinga cateniformis and Ochroma pyramidale seeds seedlings in response restoration. seed viability test performed using 1 % tetrazolium (2,3,5-triphenyl chloride) during three staining times percentage vigor levels were considered according topological pattern. Germination speed, germination capacity, morpholog...

This paper describes an investigation into the cross-sectional behaviour of elliptical hollow section (EHS) columns made from ferritic and duplex stainless steel. The EHS is a relatively new structural shape with number favourable attributes including aesthetic appeal, high strength-to-weight ratio, good torsional resistance excellent flexural strength. In recent years there have been significa...

Tilia amurensis Rupr. and mandshurica Maxim. are two essential commercial species, though there is surprisingly little concern about whether their branches can be used in the current situation of a wood shortage China. In this study, tissue proportions fiber morphology, physical mechanical properties, chemical composition branchwood were studied compared with stemwood to evaluate potential for ...

High-rise buildings subjected to lateral loads such as wind and earthquake loads must be checked not to exceed the limits on the maximum lateral displacement or the maximum inter-story drift ratios. In this paper, a sensing model for deformed shapes of a building structure in motion is presented. The deformed shape sensing model based on a 2D scanner consists of five modules: (1) module for acq...

This contribution deals with a self-consistent description of time-mean turbulent lubricant flow, i.e. flow through a wedge-shaped gap confined by counter-sliding solid surfaces. The methods adopted are matched asymptotic expansions, where the slenderness or aspect ratio of the gap and the accordingly defined Reynolds number represent the perturbation parameters. As a remarkable result, a load-...
