An experimental investigation on the lateral collapse behaviour of woven fabric glass/epoxy composite tubes under quasi-static and impact loads are presented here. Composite tubes of different diameter to thickness ratios (D/t = 5.33 - 20.67) were compressed between two flat platens or by a short width square indenter. Impact tests were performed at the gravity drop hammer test setup. The fracture process and the energy absorption capability of the composite tubes under quasi-static and impact loads were studied. It was observed that, the lateral collapse mechanism of thick composite tubes (D/t < 10) was different from thinner tubes (D/t > 10). Finally, the progressive failure analysis of the composite tube was performed in finite element software ABAQUS. Good agreement was observed between the experimental results and numerical predictions.

This paper analyzes the working behavior characteristics of a prestressed concrete transverse large cantilever continuous (PCTLCC) box girder bridge model based on structural stressing state theory and the numerical shape function (NSF) method. At first, the normalized generalized strain energy density (GSED) is established to model the stressing state of the bridge model. Subsequently, the Mann Kendall (M–K) criterion is applied to detect three characteristic loads, respectively, elastic–plastic branch load P (200 kN), failure load Q (300 kN), and progressive failure load H (340 kN), and the failure load Q is found to be the starting load of the damage process of the bridge model, rather than the ultimate load where the structure has been destroyed. Finally, the NSF method is adopted to interpolate the test data, and a detailed analysis for the variation characteristics of the working behavior of the bridge model under loads is performed based on the interpolation results. The characteristic load detection method and experimental data extension method for PCTLCC box girder bridge established in this study can provide valuable references for the design and analysis of such bridges.

This report reviews theoretical investigations which have been conducted to determine the behaviour of reinforced concrete, prestressed concrete and structural steel elements subjected to well defined repeated and reversed loading of high intensity. It commences with a brief summary of the stress-strain characteristics of the materials under such loading in the plastic range and then reports on theoretical methods for determining the moment-curvature and load-displacement characteristics of the members. Some consideration is also given to complete structures. Areas where future research is necessary are indicated.
