Beam-Truss Models to Simulate the Axial-Flexural-Torsional Performance of RC U-Shaped Wall Buildings
نویسندگان
چکیده
Reinforced concrete (RC) core walls are commonly used to provide buildings with lateral and torsional resistance against the actions of wind earthquakes. In low-to-moderate seismic regions, it is not unusual find a single peripheral wall that alone should resist these actions, where (rotational) twist cannot be neglected. It has previously been difficult have confidence in simulating axial-flexure-torsion behavior RC walls, primarily due to: (i) some types modelling approaches being unable appropriately account for shear-flexural action, as well response; (ii) scarcity experimental data, particularly under loads, which would required validate such models. this research, beam-truss models (BTMs), correspond an interesting compromise between detailed practical applications, were simulate in-plane diagonal flexural response U-shaped walls. Furthermore, global torque-rotation results from recent test provided evidence further powerful technique. A case study building, comprising structure varying eccentricity values, was evaluated earthquake event 2475-year return period city Melbourne, Australia, using capacity spectrum method. Nonlinear static pushover analyses showed that, depending on magnitude torsion, strength displacement can significantly reduced. The research emphasize importance including design assessment reinforced buildings.

چکیده هدف اصلی از طراحی لرزه ای تامین ایمنی جانی در هنگام وقوع زلزله و تعمیر پذیر بودن سازه خسارت دیده، پس از وقوع زلزله است. تجربه زلزله های اخیر نشان داده است که ساختمان های طراحی شده با آیین نامه های مبتنی بر نیرو از نظر محدود نمودن خسارت وارده بر سازه دقت لازم را ندارند. این امر سبب پیدایش نسل جدید آیین نامه های مبتنی بر عملکرد شده است. در این آیین نامه ها بر اساس تغییرشکل های غیرارتجاعی ...

In many countries of moderate to high seismicity, reinforced concrete (RC) core walls are used as lateral bracing systems in midto high-rise buildings where they typically accommodate lift shafts or stair cases. Unlike planar walls which provide horizontal strength and stiffness mainly in the in-plane direction of the wall, core walls provide bidirectional strength and stiffness. This feature c...
متن کاملEffect of seismic sequences on fragility of Iranian code-conforming shear wall RC buildings
Background and objective: Estimating the vulnerability rate of urban textures in seismic incident following a major earthquake (aftershocks) is crucial in decision making and crisis management. For this purpose, it is necessary to calculate the vulnerability of buildings due to the successive incidents and to use them in the vulnerability estimation for probable future aftershocks. Seismic frag...
متن کاملInverse U-shaped curve for age dependency of torsional eye movement responses to galvanic vestibular stimulation.
To investigate age dependent changes we analysed torsional eye movement responses to binaural and monaural galvanic vestibular stimulation (GVS) in 57 healthy subjects (20-69 years old). GVS (1-3 mA) induced torsional eye movements consisting of static torsion toward the anode (amplitude 1-6 degrees ) and superimposed torsional nystagmus (slow phase velocity 0.5-3 degrees /s, quick phase amplit...
