Fatigue of a composite girder according to Eurocode 4 is carried out on the decisive shear connector. It not taken into account that an internally highly statically indeterminate system in which failure dowel does necessarily lead girder. This applies particular dowels are characterised by crack propagation phase with high residual load-bearing capacity damaged dowel. In own small part and test...

Enhancing the ease of construction fillers and large-span floors their overall mechanical performance is critical for prefabricated hollow slabs in modular building structures. Therefore, we propose a novel assembly integral two-way floor structure (8.4 × 8.4 m) consisting permanent (BDF ribbed steel mesh box) three precast one-way hollow-core with I-shaped flexural sections to address above pr...

Composite shell linings consist of primary and secondary sprayed concrete linings separated by a layer of spray-applied waterproofing membrane. In order to design such a lining configuration, a calibrated numerical simulation approach is needed and the impact of interface properties on the composite mechanical behaviour should be understood. A programme of laboratory tests was carried out on be...

The results of hydrogenation of single walled carbon nanotubes (SWCNTs)-SnO2 composite thin film is reported here. SWCNTs mixed with SnO2 by weight are made into pellet without any binder. Then, the pellet is evaporated by electron beam on glass substrates at room temperature in hydrogen atmosphere. The amount of hydrogen incorporated in the SWCNTs-SnO2 composite is found to be 2.4 wt.%. In add...

This paper is concerned with the development of new simple 4-noded locking-alleviated smart finite elements for modeling the smart composite beams. The exact solutions for the static responses of the overall smart composite beams are also derived for authenticating the new smart finite elements. The overall smart composite beam is composed of a laminated substrate conventional composite beam, a...

It has been argued that the AASHTO LRFD design code for maximum live loads on highway bridges is overly conservative. In an attempt to determine the level of conservativeness, if any, the writers developed a methodology incorporating real-time visual data collection from traffic cameras coupled with structural strain response of girder bridges. Average daily truck traffic along with frequency o...

In this study, the complex behavior of steel encased reinforced concrete (SRC) composite beam–columns in biaxial bending is predicted by multilayer perceptron neural network. For this purpose, the previously proposed nonlinear analysis model, mixed beam-column formulation, is verified with biaxial bending test results. Then a large set of benchmark frames is provided and P-Mx-My triaxial ...

the finite element method is employed for the flexural-torsional linear buckling analysis of beams of arbitrarily shaped composite cross-section taking into account generalized warping (shear lag effects due to both flexure and torsion). the contacting materials, that constitute the composite cross section, may include a finite number of holes. a compressive axial load is applied to the beam. the...
