The steel racks on the floor are seen as live loads in current design process, ignoring interaction with supporting frames. In this paper, multiple different masses and stiffnesses placed first of a two-story main structure to form real structures (RS). corresponding simplified (SS) frames mass concentrated structure. Modal analysis is performed analyze relationship between periods RS SS cross-...
A Study of the Essence of the Cinematic Frame According to the Metaphors of the Window and Framework
The cinematic frame is the boundary between the cinematic image and the outside world. In the history of theoretical studies of cinema, the essence of the cinematic frame is analyzed in many ways. Here we focus on two significant viewpoints among them. One of these significant viewpoints considered cinematic frame as a window, and another one considered it as a framework. Both of them had (and ...
this paper describes experimental and numerical investigations on two specimens of frames composed of steel reinforced concrete beam and angle-steel concrete column under horizontal low cyclic loading. based on the test results, the relationship curves of the horizontal load-displacement and the failure modes are acquired. meanwhile the hysteretic behaviors, skeleton curves, stiffness degradati...
Steel Plate Shear Wall (SPSW) is an emerging seismic load-resistant system that, compared to other systems, enjoys the advantages of stable ductile behavior, fewer detailing requirements, rapid constructability, and economy. American seismic provisions decree that a SPSW should be designed as a moment frame with a web infill plate. Specifically, in case of buildings taller than 160 ft, it decre...
Elevated water tanks supported by the reinforced concrete (RC) Staging are classified as inverted pendulum structures. These are considered as structures of high post-earthquake importance and should remain functional after the seismic events. National codes of various countries recommend Force-Based Design (FBD) procedure for water tank staging, which does not ensure nonlinear performance leve...
in this paper we get some results and applications for duals and approximate duals of g-frames in hilbert spaces. in particular, we consider the stability of duals and approximate duals under bounded operators and we study duals and approximate duals of g-frames in the direct sum of hilbert spaces. we also obtain some results for perturbations of approximate duals.
in this paper, g-dual function-valued frames in l2(0;1) are in-troduced. we can achieve more reconstruction formulas to ob-tain signals in l2(0;1) by applying g-dual function-valued framesin l2(0;1).
