Study on the Wind Environment and Pollution Diffusion of Building Group Based on LES Staggered Joint Arrangement
Publisher: ASCE
Abstract: In this paper, computational fluid dynamics (CFD) numerical simulation and wind tunnel tests are used to study the wind environment of typical buildings in coastal cities. Firstly, the geometric three-dimensional model is ...
Simultaneous Assessment of Damage and Unknown Input for Large Structural Systems by UKF-UI
Publisher: ASCE
Abstract: Much progress has been made in the assessment of structural damage and unknown input (UI) using incomplete and noisy measurement signals. The unscented Kalman filter (UKF) has proved to be a sophisticated approach to this ...
Structural Damage Diagnosis Based on the Temporal Moment of Partially Measured Structural Responses
Publisher: ASCE
Abstract: Structural damage diagnosis is still a challenging task because most current methods are either insensitive to local structural damage or sensitive to measurement noise. A statistical moment–based structural damage detection ...
Identifying Distributed Dynamic Loading in One Spatial Dimension Based on Combing Wavelet Decomposition and Kalman Filter with Unknown Input
Publisher: ASCE
Abstract: The identification of distributed dynamic loads is an important but challenging task because a distributed dynamic load is composed of both time and space functions. This paper proposes a novel method for the identification ...
State-Input System Identification of Tall Buildings under Unknown Seismic Excitations Based on Modal Kalman Filter with Unknown Input
Publisher: ASCE
Abstract: The seismic safety evaluation of tall building structures is necessary, but the multidegree-of-freedom feature of tall buildings increases the difficulty of joint identification of structural states, structural parameters, ...
Identification of Distributed Dynamic Loads in Gradually Varying Two Spatial Dimensions Based on Discrete Cosine Transform and Kalman Filter with Unknown Inputs
Publisher: ASCE
Abstract: The identification of two-dimension distributed dynamic loads using partial structural responses is still challenging. In this paper, a method is proposed to identify the gradually varying spatial distribution functions ...
Identification of Natural Frequencies and Dampings of In Situ Tall Buildings Using Ambient Wind Vibration Data
Publisher: American Society of Civil Engineers
Abstract: An accurate prediction for the response of tall buildings subject to strong wind gusts or earthquakes requires the information of in situ dynamic properties of the building, including natural frequencies and damping ratios. ...
Parallel Substructure Identification of Linear and Nonlinear Structures Using Only Partial Output Measurements
Publisher: ASCE
Abstract: Substructure identification with the idea of divide and conquer has played a significant role in the identification of large-scale structures. Nevertheless, most existing substructure identification methods are only used ...
