When designing thin-walled aircraft structures, as a rule, the main limitations are associated with ensuring stability. The objects of research in this work composite z-shaped reinforced panels wing box an aircraft. For early stages design load-bearing panels, it is necessary to evaluate weight decisions made, taking into account possible defects. paper proposes analytical technique for use con...

Thermal modification is a well-known process to change the dimensional stability, hygroscopicity, and biological resistance of wood due to chemical modifications of wood cell components. In this study, we reviewed several characteristics of heat-modified solid wood and wood-based panels under various temperatures, durations and pressure. Thermal compressing treatment could affect drying speed, ...

Fourteen composite honeycomb sandwich panels were tested to failure under compressive loading. The test specimens included panels with both eight and twenty-four ply graphite-bismaleimide composite facesheets and both titanium and graphite-polyimide core materials. The panels were designed to have the load introduced through fasteners attached to pairs of steel angles on the ends of the panels ...

This is the first study on the free vibrational behavior of sandwich panels with flexible core in the presence of smart sheets of oil which is capable of the excitation of magnetic field. In order to model the core, the improved high order theory of sandwich sheets was used by a polynomial with unknown coefficients first degree shear theory was used for the sheets. The derived equations based o...

We have developed the new hybrid structure of CLT infill and steel frame for middle-rise high-rise buildings. This structural system can achieve high potential panel by holding around with frame. Steel support sustained load a building without panels build long-span beams reasonably. Compression stress seismic be transmitted to upper bottom through strength mortal layer, secure shear as boundar...

This paper presents experimental investigations carried out on various composite floor deck panel systems. The effects of parameters such as concrete shear length, steel thickness, and thickness the flexural behavior panels were examined. Shear tests identical specimens with four different span lengths. Four-point single-span double-span specimens. stress-slip, load-deformation, moment-curvatur...

This paper reports the results of three thin wythe precast sandwich panels tested under axial load. Panel reinforcements and shear connectors in current state civil construction context are evaluated. The authors measured displacement at two distinct panel heights as well along width to provide load–displacement behavior cross-section level broaden experimental data on subject. test developed t...
