Earthquake risk (prone) buildings

open access: yesBulletin of the New Zealand Society for Earthquake Engineering, 1996
Recent completion of the Earthquake Risk (Prone) survey of unreinforced masonry buildings in the Gisborne District provides an opportunity to review the results achieved and, bearing in mind the re-draft of the Red Book, reflect on observed behaviour of local buildings in two "moderate" or close to "moderate" earthquakes.

Experimental and constitutive modeling investigations on marble in Jinping Underground Laboratory

open access: yesDeep Underground Science and Engineering, EarlyView.
The objective of this study is to reveal the underlying mechanisms behind the brittle‐ductile transition of the marble through a combination of experimental research and constitutive modeling. A series of triaxial compression and triaxial cyclic loading tests are conducted.

Characterization of the permeability evolution of hard and soft rocks under hydro‐mechanical coupling conditions

open access: yesDeep Underground Science and Engineering, EarlyView.
The permeability variation of rocks during complete stress–strain processes was investigated. A mathematical model describing the influence of rock damage on permeability was constructed. The permeability–stress relationship between soft rock and hard rock was proposed.

Probability prediction of true‐triaxial compressive strength of intact rocks based on the improved PSO‐RVM model

open access: yesDeep Underground Science and Engineering, EarlyView.
In this work, we propose an improved particle swarm optimization (PSO) algorithm and develop an improved PSO‐relevance vector machine (RVM) model as a substitute for traditional true‐triaxial testing. The model's high prediction accuracy was validated through comparisons with two other machine learning methods and five three‐dimensional Hoek–Brown type

Mechanical property variation mechanisms of granite subjected to real‐time high temperatures and subsequent cooling treatment

open access: yesDeep Underground Science and Engineering, EarlyView.
This study investigates the coupled thermo‐mechanical behavior of granite during heating and cooling through a combination of laboratory tests and finite element analysis. The thermal conductivity, mineral composition, mass loss rate, micro‐crack observation, and thermal fracture characteristics of granite under various temperature conditions are ...

Machine-learning detection of slow slip events in western Shikoku, Japan, through joint analysis of seismic and geodetic data

open access: yesEarth, Planets and Space
Over the past decade, short-term slow slip events (S-SSEs) have been detected along the entire Nankai Trough using Global Navigation Satellite System (GNSS) data.

Identifying and prioritizing the factors affecting the increase of earthquake risk in worn-out urban areas with a combined approach of fuzzy Delphi technique and BMW model [PDF]

open access: yesتحقیقات کاربردی علوم جغرافیایی, 2020
Today, the vulnerability of cities, especially the old and worn-out tissues to earthquakes, has become a global issue for experts in various fields. This situation has become more acute in countries with dangerous natural structures, including Iran, in ...
