Allocation of Actuators and Sensors for Coupled-Adjacent-Building Vibration Attenuation

IEEE Transactions on Industrial Electronics, 2013
An actuator and sensor allocation approach is proposed for the design of coupled-adjacent-building vibration suppression under seismic excitation. This paper first establishes a full-order model of adjacent buildings with the location information of actuators and sensors. Then, the order of the model is reduced via modal cost analysis, by retaining the

Cracking in Walls of a Building Adjacent to a Deep Excavation

Journal of Performance of Constructed Facilities, 2011
A major concern for projects involving deep excavations in urban areas is the response of adjacent buildings and utilities to excavation-related ground movements. Unfortunately, a purely theoretical approach to estimating building response to excavation-related deformations is not possible due to the variability of the many factors that contribute to ...

Probability analysis of seismic pounding of adjacent buildings

Earthquake Engineering & Structural Dynamics, 2001
AbstractThe need to investigate the level of seismic pounding risk of buildings is apparent in future building code calibrations. In order to provide further insight into the pounding risk of adjacent buildings, this study develops a numerical simulation approach to estimate the seismic pounding risk of adjacent buildings separated by a minimum code ...

Reduction of train-induced vibrations on adjacent buildings

Structural Engineering and Mechanics, 2001
In this paper, the procedure for deriving an infinite element that is compatible with the quadrilateral Q8 element is first summarized. Enhanced by a self mesh-expansion procedure for generating the impedance matrices of different frequencies for the region extending to infinity, the infinite element is used to simulate the far field of the soil ...

Spectral analysis on pounding probability of adjacent buildings

Engineering Structures, 2001
Presented herein is a spectral approach to evaluate the seismic pounding probability of two adjacent buildings simulated by multi-degree-of-freedom systems and separated by a minimum code-specified separation during a period of time. The analytical approach is based on random vibration theory and total probability theory.

Analysis of seismic pounding between adjacent buildings

Australian Journal of Structural Engineering, 2015
AbstractSeismic poundings between inadequately separated buildings have been observed in most previous major earthquakes. Pounding usually caused local damage around the impacting areas, and in extreme cases, collapse of the building structures. AS1170.4-2007 requires the separation between adjacent buildings to be at least 1% of the building height to

Impact of Adjacent Building on Outdoor Ventilation around a Layout of Two Buildings

Applied Mechanics and Materials, 2016
The outdoor air ventilation impact of a taller building in different configurations of a layout of two adjacent buildings is presented in this paper. The critical parameters investigated are the separation distance (S) between the buildings and the ratio of height of downwind building to that of the building upwind, herein referred to as building ...

Wind Pressure Coefficients for Different Building Configurations with and without an Adjacent Building

International Journal of Ventilation, 2006
AbstractThe design protocol for wind-driven cross ventilation in buildings should include two processes, namely the determination of required ventilation rate to reduce the room temperature and the prediction of the ventilation rate resulting from the arrangement of openings and wind pressure on those.

Variability of cladding pressures caused by adjacent buildings

Journal of Wind Engineering and Industrial Aerodynamics, 1998
Abstract A question that arises in wind tunnel testing of buildings is how to take into account the changes in wind load that might occur as a result of future buildings being built nearby or existing buildings being demolished. This paper addresses this question in so far as it affects cladding loads.
