Ganodermataceae is a remarkable group of polypore fungi, mainly characterized by particular double-walled basidiospores with a coloured endosporium ornamented with columns or crests, and a hyaline smooth exosporium. In order to establish an integrative morphological and molecular phylogenetic approach to clarify relationship of Neotropical Amauroderma s.lat. within the Ganodermataceae family, m...

The concept of cold-formed light steel framing construction has been widespread after understanding its structural characteristics with massive research works over the years. Connection serves as one of the important elements for light steel framing in order to achieve its structural stability. Compared to hot-rolled steel sections, cold-formed steel connections perform dissimilarity due to the...

Addition of steel fibers to high strength concrete (HSC) improves its post-peak behavior and energy absorbing capability, which can be described well in term of toughness. This paper attempts to obtain both analytically and experimentally the efficiency of steel fibers in HSC columns with hybrid confinement of transverse reinforcement and steel fibers. Toughness ratio (TR) to quantify the confi...

Abstract To improve the behavior of hollow concrete filled steel tube, a novel type reinforced circular tubular member (RHCFST) was put forward and its axial studied. The finite element analysis model 12 RHCFST short columns under compression established by using ABAQUS. influence tube’s strength wall thickness, diameter bar with normal strength, sandwich concrete’s thickness on mechanical prop...

Hollow sections have been widely used for steel structures. Applications of High Strength Steel (HSS) on cold-formed hollow sections lead to thinner and lighter structures. This paper presents numerical investigations on the lateral-torsional buckling resistance of the cold-formed high strength steel rectangular hollow beam. Results from finite element analysis using Abaqus software are compare...

Structural fuses, easily replaceable sacrificial elements to dissipate seismic energy while preventing damage to the gravity loadresisting structural system, are proposed as part of a multicolumn accelerated bridge construction (ABC) pier concept. Different types of structural fuses are investigated to compare the effect of each on ABC bridge bents. The piers of a three span-continuous bridge p...

Concrete-filled double skin steel tubular columns consisting of two hollow tubes and concrete infill between their interspace, have become popular in modern construction owing to high ultimate load, less self-weight good ductility. The weight these can be reduced further by using lightweight aluminium alloy instead ones. This paper experimentally numerically studied the flexural buckling behavi...
