Non-Linear Static Analysis of Masonry Buildings under Seismic Actions [PDF]

Journal of Systemics, Cybernetics and Informatics, 2018
Assessing existing masonry buildings in seismic zones is a critical issue, due to the high vulnerability of the built environment. Commonly, beside local analysis, refined assessment procedures are used based on non-linear static methods, like the ...

Seismic Performance Evaluation Of Momentresisting Steel Frames With Two Softwares

مجلة العلوم البحتة والتطبيقية, 2020
Moment resisting steel frames (MRSF); which are widely used as lateral load Resisting systems for low- to medium-rise buildings; are one of the simplest ductile systems that can be built without bracing elements.

Implications of heterogeneous embankment conditions for geoelectrical investigations on dams: A case study at Mactaquac Dam, Canada

Near Surface Geophysics, EarlyView.
Abstract Electrical resistivity tomography (ERT) has been shown to be effective for surveying and monitoring dams, due to the method's sensitivity to moisture content and relevant physical properties (e.g., porosity). Automated ERT systems, capable of time‐lapse monitoring, can be used to detect variations in ground conditions.

Robust β‐myrcene block copolymer elastomeric vitrimers

Polymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

FORCE/TORQUE PUSHOVER METHOD FOR PLAN IRREGULAR STRUCTURES

, 2008
In the present study, a new pushover procedure for seismic static analysis of plan irregular 3D frame structures is proposed, based on the application of a set of horizontal force and torque distributions at each floor level. In order to predict the most

Near‐resonant excitation of the Adriatic barotropic modes: The seiche events of December 2019

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study examines severe flooding in the northern Adriatic Sea in December 2019, which existing forecasting systems failed to predict. Analysis of wind and sea‐level data, alongside reanalysis datasets and a high‐resolution hydrodynamic model, revealed a wind‐induced resonance mechanism.

A new method to identify and explain sources of precipitation modification, illustrated for the western Netherlands

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study develops a method to identify the source areas of precipitation events, as illustrated for the western part of the Netherlands. Radar‐based precipitation data are traced back to their source areas and machine‐learning techniques are used to identify hypothesized causes: urban heat, surface roughness, and air pollution. We find that urban and

Modulation of wind drag by tidal currents in an embayment

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Tidal currents modulate how wind energy enters the surface wave field by influencing both wave drag and wave generation. In Shark Bay, following currents reduce effective wave steepness and wind drag, and opposing currents enhance wave growth. Wind energy is partitioned between wave drag and the creation of new waves, explaining observed tidal ...
