A Memristive-System-Based Hysteresis Model for a Compact Pneumatic Artificial Muscle

Actuators
Pneumatic artificial muscles exhibit pronounced hysteresis in the force-contraction domain, which complicates accurate force modeling under pressure-dependent operation.

Experimental Study on Stiffness Degradation and Hysteretic Behavior of Rock-Filled Concrete under Uniaxial Cyclic Compression Loading [PDF]

长江科学院院报
[Objective] Rock-filled concrete (RFC) is inevitably subjected to repeated loading-unloading processes during service. However, studies on the stiffness degradation and hysteretic behavior of RFC under cyclic loading remain limited.

Experimental investigation of reinforced concrete members subjected to reversed cyclic axial loading

Structural Concrete, Volume 27, Issue 3, Page 3838-3860, June 2026.
Abstract This paper presents an experimental campaign of five reinforced concrete members subjected to cyclic axial loading alternating between tension and compression. Fiber optical sensors and digital image correlation, in combination with automated crack detection and measurement, were used to investigate, among other aspects, the development of ...

Analytical Floor Response Spectra for Performance‐Based Seismic Design of Non‐structural Elements in Reinforced Concrete Frame Buildings

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 6, Page 1292-1312, May 2026.
ABSTRACT Damage to non‐structural elements significantly impacts the seismic performance of buildings in terms of economic and functionality losses. Consequently, performance‐based seismic design of non‐structural elements has become a key pillar of a comprehensive building‐seismic resilience strategy, for instance, through loss‐targeted earthquake ...

Numerical Simulation of Post‐Yield Hysteretic Behavior of Lap‐Spliced Reinforced Concrete Bridge Pier Walls Under Earthquake Loading

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 6, Page 1356-1376, May 2026.
ABSTRACT Reinforced concrete pier walls designed before the 1970s often incorporate lap splice in potential plastic‐hinge regions. Previous experimental tests indicate that most of pier walls experienced post‐yield lap splice failure, necessitating a modeling approach that captures not only lap splice strength but also deformation capacity.

Achieving Functionality Targets for Seismically Isolated Steel Buildings Using Gaussian Process Modeling

Earthquake Spectra, Volume 42, Issue 2, May 2026.
As seismic design paradigms shift toward functional recovery, there is a need for efficient methods to achieve desired decision variables (DVs), such as probability of replacement, repair cost, and downtime of the building, for seismically isolated buildings.
