Research on the response of concrete cavity shear wall under lateral load

“…Compared with the cast‐in‐place concrete, the overall performance of the assembly structure is often questionable due to the joint part of the old and new concrete, resulting in poor seismic performances, which has become the weakness in terms of its promotion . In order to meet the seismic requirements of high‐rise buildings, there have been many studies on the seismic performance of assembly structures …”

“…[17] In order to meet the seismic requirements of high-rise buildings, there have been many studies on the seismic performance of assembly structures. [18][19][20][21][22] In view of the low shear-span ratio shear wall and the stress characteristics of open vertical slit shear wall and hollow shear wall, the cavity shear wall is put forward in this paper, as shown in Figure 1. The self-weight and stiffness of the cavity shear wall can be reduced; the seismic performance can be largely improved.…”

Shaking table test and numerical simulation of a superimposed reinforced concrete shear wall structure

“…The representative research work is listed as follow: Oliva et al conducted a shaking table test and numerical simulation of three three‐story one‐third scale models of precast concrete slab; Soudki carried out cyclic loading tests on the horizontal seams of the precast concrete slab whose vertical reinforcement connected with each other differently. Based on 29 specimens, the shear strength of vertical seam was studied by Chakrabarti . Pakau et al set friction‐type mechanical connection components at the seams to improve the seismic performance of precast concrete slab structure and analyzed the impact of friction on the horizontal seams.…”

“…Based on 29 specimens, the shear strength of vertical seam was studied by Chakrabarti. [20] Pakau et al [21] set friction-type mechanical connection components at the seams to improve the seismic performance of precast concrete slab structure and analyzed the impact of friction on the horizontal seams. The above studies show that the elastic deformation of the precast concrete slab structure under strong earthquake is dominated by the rocking deformation, and the horizontal seams between the shear wall and the foundation gradually form continuous seams under seismic actions.…”

Numerical Simulations of a Two Component Advective Flow for the Study of the Spectral and Timing Properties of Black Holes

“…Numerous suggestions and cartoon diagrams of the illusive The presence of Compton cloud are shown in the literature (e.g., Zdziarski, 1988 ;Haardt et al, 1994 ;Chakrabarti & Titurchuk, 1995 ; Hereafter CT95). CT95, based on the solutions of viscous and inviscid transonic flows around black holes (Chakrabarti, 1989;Chakrabarti 1990) proposed that, in general, the accretion disk should really have two components: a Keplerian accretion on the equatorial plane and a sub-Keplerian halo which surrounds the Keplerian disk, and the puffed up inner part of the flow (CENBOL) which is nothing but the Compton cloud. There was as yet no work in the literature to show that the Two Component Advective Flow (TCAF) solution is stable.…”
