Empirical Methodology

An empirical methodology to evaluate damage by the use of two damage indicators for 2D steel/concrete composite structures is proposed. This methodology has been established with aid of the results of an extensive parametric study regarding the non-linear behaviour of 48 steel/concrete composite frames subjected to 100 far-fault records. A large number of inelastic dynamic analyses are conducted by increasing the earthquake motions to lead the frames to several levels of non-linear response. The results of the analyses show that the characteristics of the structure and the ground motions affect damage of the structures. The results are post-processed by the use of statistical methods to generate expressions, which show the effect of the abovementioned parameters and give an evaluation of the damage indicators utilised here. In particular, given the characteristics of the frames and the record, someone can compute the maximum damage found in beams and columns. Finally, one example serves to show the use of the developed formulae and demonstrates their validity.

Analysis Design

Composite timber-masonry walls have been used in many old traditional and preservable buildings that constitute a significant part of the world cultural heritage. In this structural system the walls are composed by a timber substructure that is filled by masonry with (or without) mortar. The response of these walls to any static or dynamic loading, even of small intensity, is generally non-linear, mainly due to the complex interaction between the timber and masonry components. It is obvious that the analysis, design, strengthening and retrofitting of these composite structures demand a quite complex, reliable and effective structural model that can take into consideration all the above mentioned construction details and sources of non-linear behaviour. In the present study such a precise analytical micromodel for this structural system is further developed and demonstrated with application examples.

In order to promote the efficient use of composite materials in civil engineering infrastructure, effort is being directed at the development of design criteria for composite structures. Insofar as design with regard to behavior is concerned, it is well known that a key step is to investigate the influence of geometric differences on the non-linear behavior of the panels. One possible approach is to use the validated numerical model based on the non-linear finite element analysis (FEA). The validation of the composite panel’s element using Trim-deck and Span-deck steel sheets under axial load shows that the present results have very good agreement with experimental references. The developed finite element (FE) models are found to reasonably simulate load-displacement response, stress condition, giving percentage of differences below than 15% compared to the experimental values. Trim-deck design provides better axial resistance than Span-deck. More concrete in between due to larger area of contact is the factor that contributes to its resistance.
