Multi-objective Performance Based Control of Building Frames during Wind and Earthquake Events for Multi-Hazard Mitigation using a New Hybrid Passive Energy Dissipation Device
Bibliographic record
Abstract
The paper presents a performance based design approach employing a new hybrid passive energy dissipation (PED) device for multipurpose vibration control of Reinforced Concrete (RC) building frames in a multi-hazard environment subjected to critical wind and earthquake events.A versatile and innovative hybrid PED device is proposed in the present study for controlling a broad range of wind and earthquake induced structural vibrations in a multi-hazard scenario.The proposed hybrid PED device implements a novel combination and assembly of viscous and friction elements along with a slip-lock element for controlling the low as well as high amplitude structural vibrations by dissipating the input wind or seismic energy in both low and high intensity multi-hazard events.The viscous element in the hybrid PED device reduces the structural response from the onset of structural vibrations during mild to moderate wind or earthquake events in which the friction element remains inactive.On the other hand, the friction element in the hybrid PED device is activated only in the event of extremely strong winds or severe earthquakes that surpass the slip load of the friction element.Simulated case studies are conducted to numerically evaluate the efficacy of the proposed new hybrid PED device for performance based structural control of RC building frames subjected to a wide range of wind and earthquake induced excitations.Preliminary results of the numerically simulated case studies presented in the paper demonstrate that in principle, the proposed hybrid PED device can be designed using an Energy based plastic design method in the performance based design (PBD) framework for effectively controlling the vibration response of building frames under the action of dynamic wind and earthquake loads within the respective limiting values recommended by published design standards on performance based wind engineering and performance based earthquake engineering of buildings for various performance limit states and hazard levels.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
