The document concerns with the design and study of a large masonry model of Hagia Irene in Istanbul. The goals of experimentation were to acquire a deeper structural behaviour knowledge than that possible to acquire with numerical models only and to assess the effectiveness of the consolidation works foreseen on Hagia Irene. The scale factor chosen is equal to 1:10. The tests were arranged into two different phases: for not reinforced and reinforced scale model .The displacements of the markers placed on the structure were registered by an innovative monitoring technique measuring 3D motion time histories.

Story Building

<p>The paper discusses results of shaking table tests on an in-scale high-rise building model. The purpose was to calibrate a dynamic numerical model for multi-hazard analyses to investigate the effects of floor acceleration. Accelerations, because of vibration of non-structural elements, affect both the comfort and safety of people. The research investigates the acceleration effects of both seismic and wind forces on an aeroelastic in-scale model of a multi-story building. The paper discusses the first phase of experiments and gives results of floor accelerations induced by several different base seismic impulses. Structural analyses were first performed on the full-scale prototype to take soil-structure interaction into account. Subsequently the scale model was designed through aeroelastic scale laws. Shaking table experiments were then carried out under different base accelerations. The response of the model and, in particular, amplification of effects from base to top are discussed.</p>

Before And After

The influence of the natural hydraulic lime-based grout on the dynamic behaviour of injected multi-leaf stone masonry elements is discussed in the paper. Shaking table experiments on two stone masonry buildings, tested before and after grout injection, have been performed. The paper focuses on the analysis of both the recorded accelerations and related displacements, at the bottom and at each further storey. This leads to evaluate the stiffness of the unstrengthened and injected structures. The input at increasing PGA allowed the stiffness decay to be studied, simulating a gradual damaging of the structures. These results were also interpreted in the light of both computed frequencies and mode shapes. Finally, the comparison among these results, obtained from all the models, allows to deepen the knowledge concerning the effects induced by the lime-based grout injection and on its capability to modify the dynamic behaviour, when intervening on a damaged (repairing) or on an undamaged (strengthening) structure.

This paper reports the results of the second phase of a research program that carried out shaking table tests on a scale model of a typical stone masonry temple. This second phase evaluates the efficacy of two different retrofitting techniques by comparing the response of the retrofitted models with that of the original unreinforced model. It was found that both retrofitting schemes substantially enhanced the performance of the model temple. The maximum intensity of the base motion for which damage was considered to be still repairable increased by 80% and 120% for the first and the second levels of retrofitting, respectively. In terms of displacement capacity, the response of the model with the second level of retrofit reached a maximum drift of 0.4%. The initial damping ratios were found to be in the range of 7% to 9%, both in the original and the retrofitted models. These ratios constitute a significant source of energy dissipation for this kind of structure.

Highway System

The last four decades were important for the Brazilian highway system. Financial investments were made so it could expand and many structural solutions for bridges and viaducts were developed. In parallel, there was a significant raise of pathologies in these structures, due to lack of maintenance procedures. Thus, this paper main purpose is to create a short-term monitoring plan in order to check the structural behavior of a curved highway concrete bridge in current use. A bridge was chosen as a case study. A hierarchy of six numerical models is shown, so it can validate the bridge's structural behaviour. The acquired data from the monitoring was compared with the finest models so a calibration could be made.

This paper presents the experimental investigations into the seismic failure for high arch dam with shaking table test. The similitude scale of high arch dam was studied firstly. Then we developed a like concrete material to simulate the mechanical behavior of the structural concrete in high arch dam. The shaking table tests have been performed on the scale model. The experimental results reveal the failure process of high arch dam with respect to the different earthquake intensities.
