Weak‐Story Mitigation and Drift Redistribution in Moment‐Resisting Frames Using Stepping Rocking Walls

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2760-2780, September 2026.
ABSTRACT This study investigates the seismic response of moment‐resisting frames retrofitted with a stepping rocking wall, with emphasis on weak‐story mitigation and residual drift reduction under both ordinary and pulse‐like ground motions. Nonlinear response‐history analyses are conducted on 9‐story and 20‐story SAC Los Angeles frames.

Molecular insights and translational opportunities to enhance heat tolerance in rice

The Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Heat stress is an increasingly serious threat to rice (Oryza sativa L.) productivity, yet the genetic and regulatory architecture underlying thermotolerance remain poorly resolved and fragmented across studies. Earlier research focused on individual pathways or specific developmental stages; however, recent advances now support an integrated ...

Hygro-Thermo-Mechanical Analysis of a Reactor Vessel

Acta Polytechnica, 2012
Determining the durability of a reactor vessel requires a hygro-thermo-mechanical analysis of the vessel throughout its service life. Damage, prestress losses, distribution of heat and moisture and some other quantities are needed for a durability ...

A Study on Rational Pre-Tensioning Schemes for 60 m Prefabricated Railway Box Girders Considering Steel Formwork Constraints

Buildings
Early-age cracking is a common issue in the prefabrication of large-scale box girders, and the application of pre-tensioning techniques to introduce pre-compressive stress is an effective measure to mitigate such cracking.

Efficient Approximation Method for Concrete Creep Compliance Function

Yuanzineng kexue jishu
For concrete, the strain tends to grow when the stress is kept at a constant level. This phenomenon is usually referred to as creep. Creep is an important physical property of concrete.
