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 ...

A Comprehensive Review and Analysis of Shear Strengthening of RC Beams with External Prestressing Bars [PDF]
预应力技术Shear failure in reinforced concrete (RC) structures, characterized by their sudden and brittle nature, often results from inadequate shear reinforcement or degradation due to aging or increased loading demands.

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract To explore mechanisms of rupture segmentation, we invert coseismic GNSS offsets for the 2025 Mw 7.6 Aomori, Japan earthquake. Our preferred curved‐fault solution images a compact thrust rupture at 25–50 km depth with peak slip ∼2.5 m near 35 km.

Punching Shear Behavior of Externally Prestressed Concrete Slabs
Journal of Structural Engineering, 2011 The use of externally post-tensioned fiber-reinforced concrete decks in highway bridge structures is seen as a viable option in the move toward the design and construction of high-performance structures. However, with the thin unreinforced deck slabs that may result, punching shear is a potential concern.
