Load carrying capacity of flat double-layer space structures majorly depends on the structures' imperfections. Imperfections in initial curvature, length, and residual stress of members are all innately random and can affect the load-bearing capacity of the members and consequently that of the structure. The double-layer space trusses are susceptible to progressive collapse due to sudden buckli...

In this paper the influence of vertical component ground motion on performance an unreinforced masonry wall is analysed using sets one-component and two-component motions. The set motions represents actual seismicity L'Aquila, while investigated mimics experimental specimen with two unconnected external leaves a rubble core. model falls within mixed finite element method – discrete accounts for...

A probabilistic model to estimate the seismic risk of buildings is evaluated. For this purpose a specific methodology is proposed. The developed methodology allows explicitly consider important uncertainties that are present in the main elements, that are used to estimate the seismic risk of buildings. One of these elements is the seismic vulnerability of each building, which is mainly represen...

One of the most important problems discussed recently in structural engineering is the structural reliability analysis considering uncertainties. To have an efficient optimization process for designing a safe structure, firstly it is required to study the effects of uncertainties on the seismic performance of structure and then incorporate these effects on the optimization process. In this stud...

The article deals with the conduct of a numerical experiment on study stress-strain state building structures according to using developed mathematical models. Research methodology consists in use one most advanced BIM technologies world, namely LIRA 10.10 software complex © 2013-2021 Soft, for creating adequate models an industrial taking into account likely difficult operating conditions: loa...

After learning from several devastating earthquakes in China in recent years, stricter design criteria have been introduced in the current Chinese seismic design code. To investigate the reliability of the current seismic design code, seismic fragility analyses were performed for 45 10-story reinforced concrete (RC) frame-shear wall structures designed according to the current Chinese seismic d...

This study carried out comparative seismic performance of reinforced concrete frames infilled by masonry walls with different heights. Partial and fully infilled reinforced concrete frames were modeled for the research objectives and the analysis model for a bare reinforced concrete frame was also established for comparison. Non–linear static analyses for the studied frames were performed to in...

Wavelet and subband coding have been shown eeective techniques for seismic data compression, especially when compared to DCT-based algorithms (such as JPEG), which suuer from blocking artifact at low bit-rates. The transforms remove statistical redundancy and permit eecient compression. This paper presents a novel use of the Generalized Lapped Orthogonal Transforms (GenLOTs) for compression of ...
