Modeling, Computing and Application Particularities of no Restoring Mechanism Aseismic Control Device

Abstract

In this research presented modelling, computing and application particularities of the structural aseismic control device which response redaction effect an average 61-79% relatively to conventional structure under earthquake excitation. For modelling mention device reinforce solid, structural solid, spring and contact finite elements was used. For contact element accepted conventional Coulomb frictional model. Governing non linier equation of motion is modelled as multidegree of freedom system with discontinuous and continuous models and solved adopting direct integration algorithm with coupling of the control system and system identification toolboxes. One of the very important earthquake action phenomenon-restoring force mechanism was found out, proved and it was used for modelling a novel no restoring mechanism aseismic passive control device. Investigated control device may be economically in the simple or small scale structures because have no any restoring mechanism.

Simulation of the Response of Multi-Story Buildings with Concrete-Silica Fume and Concrete-Liquid Carbon Dioxide

“…So that the physical model of the structure is shown in Figure 2. To see in more detail the beam element is approached with standard equilibrium and kinematics [31]. With that approach, the beam element can be described in Figure 3.…”

“…With that approach, the beam element can be described in Figure 3. By using the basic concept of Euler-Bernoulli theory [31], where…”

Numerical Test of the Use of CO₂ in Multy Storey Building Structures during an Earthquake

“…A single-degree-of-freedom system is described as a spring-mass-damper system. However, to see the response of the building structure more accurately, a multi-freedom system is used [12]. This study uses the concept of a freedom system because the floor of the building to be studied is more than one floor.…”

A Comparative Study on Effectiveness of Using Horasan Mortar as a Pure Friction Sliding Interface Material

“…A number of researches have been conducted on this type of sliding material and its characteristics were experimentally studied [2][3][4]. The Natural Seismic Isolation (NSI) with Horasan mortar as the interface material was devised when the "Walled Obelisk" monument was modeled for investigation in terms of its structural safety [1,[5][6][7][8][9][10][11]. The results of the research showed that the bottom part of the monument acts as a Published on February 27, 2019.…”

“…The responses were in the range of 50-80% reduction. The responses of interest for PF systems including friction coefficient, peak sliding velocity and displacement, are shown for various other researchers [5][6][7][8][9][10][11][20][21][22][23][24]. In this study, authors aim to demonstrate the possibility to use Horasan mortar as a…”
