Recent results of in situ measurements and their interest for a seismic assessment existing buildings are presented analysed. The present paper (Part I) is devoted to the experimental programme. response ambient vibrations, harmonic excitation shock loading recorded on intact but also after structure or vicinity was modified. These tests aim identify dynamic behaviour ordinary built conventional practise. Moreover, taking advantage demolition, it possible (through these tests) determine...
This work is devoted to the study of wave propagation in infinite two-dimensional structures made up periodic repetition frames. Such materials are highly anisotropic and, because lack bracing, can present a large contrast between shear and compression deformabilities. Moreover, when thickness length ratio frame elements small, these resonate bending at low frequencies compressional waves propagate structure. The size being small compared wavelength waves, homogenization method discrete...
The interest of in situ measurements (presented Part I paper) for a seismic assessment existing buildings is analysed this paper. It shown that the experimental modal characteristics obtained on regular concrete structures are described successfully by suited Timoshenko beam modelling. For given structure, taking into account data, corresponding model, and choosing maximum tensile strain as damage criterion key structural elements, level ground acceleration can be determined. This so-called...
The dynamic behavior of discrete periodic one-dimensional structures is approached by considering transverse vibrations made repeated unbraced frames.Assuming the frame size small compared to modal wavelength, equivalent macroscopic beam descriptions are obtained homogenization method media.The parameters expressed as functions mechanical and geometrical properties elements.Depending on order magnitude (relative scale ratio) shear force, global bending inner bending, four families beams...
Titanium alloys are increasingly used in aeronautical applications, a sector that requires highly controlled materials. In particular, inclusion cleanliness is necessary and mandatory condition for safe use components. During the production processing of titanium alloys, inclusions likely to appear, particular high-density (HDIs) originate from refractory metals such as molybdenum or tungsten carbide. Plasma Arc Melting–Cold Hearth Remelting (PAMCHR) one most effective recycling refining...
Through the analysis of wave propagation in infinite two-dimensional periodic frame materials, this paper illustrates complexity their dynamic behavior. Assuming size is small compared to wavelength, homogenization method discrete media coupled with normalization used identify macroscopic behavior at leading order. The applied on a material vertical elements stiffer than horizontal elements. Such highly anisotropic and presents large contrast between rigidities possible mechanisms. Thus...
Abstract The ladle treatment of liquid steel is mainly responsible for the cleanliness, since it generates as well eliminates most oxide inclusions. Today, combination computational fluid dynamics and population balance modeling makes numerical simulation this complex three‐phase reactor possible. First, comprehensive three‐dimensional turbulent multiphase flow model developed to study behavior argon bubbles in based on geometry operating conditions corresponding real industrial process....
This paper deals with the description of modulation at large scale high frequency acoustic waves in gas saturated periodic porous media. High frequencies mean local dynamics pore and therefore absence separation usual sense homogenization. However, although pressure is spatially varying pores (according to eigenmodes), mode amplitude can present a modulation, thereby introducing another type which asymptotic multi-scale procedure applies. The approach first presented on network...
Using in-situ soils for building constructions is attractive in the sustainable development because these materials have low embodied energy and present an interesting hygro-thermal behavior. Several researches been recently carried out to study soil materials. However, variability of characteristics on each construction site makes that use unique technique (soil concrete, rammed earth, adobe, …) becomes difficult satisfy several exigencies modern regulations (mechanical, thermal...
