This paper aims to show the application of site-specific response spectra in analysis buildings that are supported by lightly reinforced precast concrete walls. Previous surveys on load-bearing walls multi-storey low-to-moderate seismic regions have found many existing with a connection reinforcement ratio less than wall ratio. When these subjected reversed cyclic loads, lateral is typically co...

abstract limitations of traditional (conventional) soil surveys and improvement of information technology have lead soil surveyors to invent new methods which are generally called digital soil mapping (dsm). the aim of these methods is the prediction of soil classes or soil properties based on easily-available or measuring environmental variables. the objective of this investigation is to study...

In the conditions of general flat stress state created by uniformly distributed effects tension (compression) at infinity, mixed contact problem for an infinite isotropic plate with a circular hole, which contour reinforced closed elastic rib in presence symmetrical interfacial section boundary their connection and edges cut process deformation is smoothly contacted, considered. The components ...

Abstract We develop a theory of finite element systems, for the purpose discretizing sections vector bundles, in particular those arising elasticity. In presence curvature, we prove discrete Bianchi identity. flat case, de Rham theorem on cohomology groups. check that some known mixed elements stress–displacement formulation elasticity fit our framework. also define, dimension two, first confor...

The aim of the work is to develop a technique on experimental study inelastic deformation structural metal materials in various types stress-strain state. A proposed based use original samples specialized complicated geometry, working zone which controlled biaxial stress state realized, and contactless 3D digital image correlation measurement system Vic-3D for recording displacement fields. aut...

In this paper energy bands and Berry curvature of graphene was studied. Desired Hamiltonian regarding the next-nearest neighbors obtained by tight binding model. By using the second quantization approach, the transformation matrix is calculated and the Hamiltonian of system is diagonalized. With this Hamiltonian, the band structure and wave function can be calculated. By using calculated wave f...

The force generated by a detergent-extracted reactivated bull sperm flagellum during an isometric stall was measured with a force-calibrated glass microprobe. The average isometric stall force from 48 individual measurements was 2.5 +/- 0.7 x 10(-5) dyne (2.5 +/- 0.7 x 10(-10) N). The force measurements were obtained by positioning a calibrated microprobe in the beat path of sperm cells that we...

Abstract The response of slender bridge piers to horizontal actions may be significantly influenced by geometric nonlinearities. In such conditions, the use sophisticated models implemented in complex structural analysis software can economically disadvantageous, especially preliminary design phases. This paper proposes a simple numerical procedure compute nonlinear pushover cantilever subject ...
