Sustained supershear rupture during the 2025 Mandalay, Myanmar earthquake

Communications Earth & Environment
The 2025 Mw 7.8 Myanmar earthquake ruptured the Sagaing fault, where sparse near-fault seismic observations limit source characterization. Here, we integrate optical imagery, InSAR, finite-fault slip inversion, back-projection (BP), and dynamic rupture ...

Surface Fault Ruptures Associated with the 1995 Hyogoken-Nanbu Earthquake.

Journal of Geography (Chigaku Zasshi), 1995
Distinctive ruptures of the surface faulting which generated the destructive 1995 Hyogoken-Nanbu Earthquake (Ms=7.2) appeared along the Nojima fault, an active fault on the northwestern coast of Awaji island, Japan. The surface fault ruptures in Awaji island extend southwestward continuously for about 9km from Easki near the epicenter to Toshima in ...

Structural behavior of small square steel tubes reinforced self‐compacting concrete columns under biaxial eccentric loads

Structural Concrete, EarlyView.
Abstract In this study, the structural behavior of small square steel tube‐reinforced self‐compacting concrete (SSTR‐SCC) columns is investigated under symmetric and asymmetric biaxial eccentric loads. Twelve specimens were cast and tested under biaxial eccentric loads.

Impacts of surface fault rupture on residential structures during the 2016 Mw 7.8 Kaikōura earthquake, New Zealand [PDF]

, 2019
Areas that experience permanent ground deformation in earthquakes (e.g., surface fault rupture, slope failure, and/or liquefaction) typically sustain greater damage and loss compared to areas that experience strong ground shaking alone.

Deflection‐based assessment of residual prestress in simply‐supported bridges accounting for creep variability

Structural Concrete, EarlyView.
Abstract Several test methods have been proposed in the literature for measuring the level of residual prestress, most of them involving either semi‐ or fully destructive techniques for local measurements which could be highly sensitive to boundary conditions and execution details.

Eco‐ductile design of RC columns: Resolving the conflict between embodied carbon and curvature ductility

Structural Concrete, EarlyView.
Abstract Reducing embodied carbon emissions in structural design is of critical importance in combating global climate change. However, the increased material usage and heavy confinement reinforcement required to meet high ductility demands in reinforced concrete columns directly conflict with environmental sustainability goals.

Strong ground motion and structural damage in the 2023 Kahramanmaraş earthquakes: A comparative case study of numerical predictions and field observations

Structural Concrete, EarlyView.
Abstract On February 6, 2023, southeastern Türkiye was struck by two catastrophic earthquakes (Mw: 7.7 and Mw: 7.6) along the East Anatolian Fault Zone, causing extensive structural failures and significant loss of life. This study evaluates the seismotectonic characteristics of the sequence, analyzes strong ground motion data against the Turkish ...

Behavior of exterior beam‐column joint reinforced with shape memory alloy

Structural Concrete, EarlyView.
Abstract Beam‐column joints are critical regions in moment‐resisting frames and are particularly susceptible to severe stress concentrations and reinforcement congestion. Conventional design typically relies on dense transverse reinforcement to improve joint performance, resulting in construction difficulties and reinforcement congestion.

Strengthening of punching shear of flat slab–column connections through hybrid near‐surface mounted and externally bonded systems: Experimental, numerical, and analytical study

Structural Concrete, EarlyView.
Abstract Slab–column connections are vulnerable to punching shear, particularly when flexural cracking reduces the effective depth. This study proposes a sustainable dual‐strengthening system to enhance punching resistance and combined flexural–punching performance.
