SEISMIC EVALUATION OF REINFORCED CONCRETE BUILDING USING NON-LINEAR TIME HISTORY ANALYSIS

Thestructure exposed to earthquake is required to show inelastic conduct that the misshaping in a part doesnt stay corresponding to the inside power. A non-direct investigation represents the inelastic reaction. Both material non-linearity and mathematical nonlinearity cases are considered. There is plastic distortion and energy assimilation in a part for more significant levels of interior power. This sort of nonlinear conduct is alluded to as material non-linearity. A few diverse hysteresis models are accessible to depict the conduct of various kinds of materials. Generally, these vary in the measure of energy they disperse in a given pattern of distortion, and how the energy dissemination conduct changes with an expanding measure of disfigurement. Turn hysteresis model is utilized. This study work utilizes fifteen-story and two cellars working of 40/60 undertaking of City Government of Addis Ababa Saving House Enterprise as a contextual investigation. A correlation is made between straight versatile examination and non-direct time history as far as story Displacement, Inter-story float, story Shear, Axial power, and Torsion. Along these lines, it ought not to be astonishing that structures endure harm during extraordinary ground shaking. The principal focal point of this work is to assess the seismic obstruction by utilizing non-direct time history investigation with the goal that the harm will be controlled satisfactorily. Seismic contribution to nonlinear unique examinations of constructions is normally characterized as far as speed increase time arrangement. Three references Earthquake Ankober 2016, EL-Centro 1940, and Sierra-Madre 1991 are utilized to create counterfeit time history utilizing time-space strategy. The time-space strategy is by and large viewed as a superior methodology for ghostly coordinating since this technique changes the speed increase time narratives in the time area by adding wavelets.

Unitarity limits on thermal dark matter in (non-)standard cosmologies

Using the upper bound on the inelastic reaction cross-section implied by S-matrix unitarity, we derive the thermally averaged maximum dark matter (DM) annihilation rate for general k → 2 number-changing reactions, with k ≥ 2, taking place either entirely within the dark sector, or involving standard model fields. This translates to a maximum mass of the particle saturating the observed DM abundance, which, for dominantly s-wave annihilations, is obtained to be around 130 TeV, 1 GeV, 7 MeV and 110 keV, for k = 2, 3, 4 and 5, respectively, in a radiation dominated Universe, for a real or complex scalar DM stabilized by a minimal symmetry. For modified thermal histories in the pre-big bang nucleosynthesis era, with an intermediate period of matter domination, values of reheating temperature higher than $$ \mathcal{O}(200) $$ O 200 GeV for k ≥ 4, $$ \mathcal{O}(1) $$ O 1 TeV for k = 3 and $$ \mathcal{O}(50) $$ O 50 TeV for k = 2 are strongly disfavoured by the combined requirements of unitarity and DM relic abundance, for DM freeze-out before reheating.

Beer Consumption in the Czech Republic and its Determinants

The study identifies the main beer consumption determinants in the Czech Republic and quantifies their influence on the beer consumption. The analysis covers three areas – identification of the main determinants of Czech beer consumption, quantification of the influence of these factors on beer consumption, and examination of beer consumption forecasting possibilities. Time series of selected variables containing annual data of the 1994–2014 period are analysed. The main determinants are defined in accord with the general economic theory, their influence is measured using an econometric model, and quality of the model for prognostic purposes is verified using an ex-post prognosis. Based on empirical analysis, the price of lager beer, income, and influence of financial crisis were determined as the main determinants of Czech beer consumption. In addition, inelastic reaction of beer consumption on their changes was proven. The estimated model may be considered suitable for prognostic purposes. The Czech beer market and/or beer consumption in the examined period can be considered as specific, but stable.

Seismic Response and Analysis of RCC Block Shear Wall in Assymetric Building Using ETABS

Shear wall is the structural member which with stand the horizontal or lateral forces. The structures are subjected to dynamic loading which have an effect on in general. Our proposed plan is to save you the structural deformation because of dynamic loading. While partitions are situated in tremendous positions in a constructing, they may be very efficient in resisting lateral masses originating from wind or earthquakes. This paper provides designated analyses of experimental and analytical has accomplished end result has generated. Our undertaking focuses on reading the impact of twist, as a system-stage impact, on the displacement and strength demands of the building’s separate seismic force resisting system (SFRS) wall components. The look at evaluates the individual wall contributions to the overall building response characteristics within both the elastic and the inelastic reaction phases.

QUANTUM DYNAMICS OF THE He + Li2 INELASTIC SCATTERING

In this paper, we report the results of three dimensional time dependent quantum wave packet calculations carried out for He+Li2 inelastic reaction in the collision energy range 0.43–1.18 eV. A three dimensional potential energy surface (PES) computed by Varandas was used for the dynamical calculations.1 The state to state and state to all transition probabilities for total angular momentum J = 0 have been calculated in a broad range of collision energies. Integral cross-sections and rate constants have been calculated from the wave packet transition probabilities by means of J-shifting approximation based on a capture model and a uniform J-shifting method for J > 0.
