Tests on eighteen small scale models which simulate the elastic and post-buckling behaviour of plate girders when subjected to shear loading are reported and discussed. Themodels were fabricated of steel and Araldite; the major aim was to assess whether small scale models can be employed to study shear buckling problems. A secondary object was to examine whether araldite could be used for predi...

Owing to their distinct features, such as structural simplicity and excellent load-carrying capacity, steel truss bridges are widely applied critical transportation networks. However, many previously designed that located in harsh environmental conditions facing severe challenges of overloading aging or deteriorating members due increasing traffic load corrosion problems (i.e., chloride-induced...

The worldwide dissemination of the pilotis multi-storey RC buildings, generally attributed to architect Le Corbusier, was contemporary with a structural engineering line thought that advocated soft first storey as means filtering down seismic inertia forces in upper storeys. These two architectural and international trends, combined outdated detailing low-code design, greatly increase risks dev...

Dammed lakes are an important secondary hazard caused by earthquakes. They can induce further damage to nearby humans. Current hydrology calculation research on dammed lakes usually lacks spatial expressive ability and cannot accurately conduct impact assessment without the support of remote sensing, which obtains important characteristic information of dammed lakes. The current study aims to a...

Native polyacrylamide gel electrophoresis is a powerful approach for visualizing RNA folding states and folding intermediates. Tris-borate has a high-buffering capacity and is therefore widely used in electrophoresis-based investigations of RNA structure and folding. However, the effectiveness of Tris-borate as a counterion for RNA has not been systematically investigated. In a recirculated Hep...

Concentrically braced frames and eccentrically braced frames are efficient seismic resistant systems but they are generally prone to develop storey collapse mechanisms. As underlined in some previous papers with regard to eccentrically braced frames, this tendency depends on the overstrength factors and damage distribution capacity factors resulting from the use of common design procedures. In ...

ABSTRACT: The bearing capacity of shallow foundations is classically computed as the sum of three contributions, coming from the soil cohesion, the overburden pressure and the weight of the soil mass mobilized by the collapse mechanism. Each of these contributive terms is then multiplied by several special corrective factors that account for the effect of the shape, depth and tilt of the founda...
