Experimental Seismic Response Assessment of Tall Buildings With Large Mass Damping

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This paper describes an experimental investigation into the seismic performance of a novel integrated damping system. The proposed damping concept mobilises a portion of the building's own mass to generate damping from its differential motion relative to the lateral load‐resisting system.

Efficacy of Double‐Tuned Mass Dampers in Reducing Higher Mode Effects in Controlled Rocking Steel Braced Frames

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This study proposes the application of double‐tuned mass dampers (TMDs) to mitigate higher mode effects in controlled rocking steel braced frames (CRBFs). A double TMD system employs two separate TMDs that can be tuned to different frequencies.

A Force‐Based Beam‐Column Element With Selective Gradient‐Inelasticity for Softening Materials in 3‐Dimensional Nonlinear Analysis

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Fiber‐based beam‐column elements featuring an effective material constitutive law with softening can capture the degrading response of structural members under extreme loading. However, these elements exhibit strain localization and mesh divergence, which impedes their accuracy.

Optimal Seismic Design of High‐Rise Buildings With Outrigger Tuned Inertial Mass Damper

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This paper presents a novel optimization method for designing a system with a tuned inertial mass electromagnetic transducer (TIMET) damped outrigger (DO) for high‐rise buildings subjected to earthquakes. The DO system consists of the TIMET devices, which attach vertically between the outrigger and the perimeter columns.

Numerical Simulations of Hydraulic Fracturing in Carbonate‐Type Hot Dry Rock Reservoirs Based on the Coupled Thermo‐Hydraulic‐Mechanical‐Damage (THMD) Model

Energy Science &Engineering, EarlyView.
ABSTRACT Hydraulic fracturing technology is widely used in Enhanced Geothermal System (EGS) projects to induce fractures and enhance the permeability of thermal reservoirs. The hydraulic fracturing process of hot dry rock (HDR) is actually a multiphysics coupling process that couples the heat transfer field, seepage field, stress field, and damage ...
