Seasonal Variability of Precipitating Systems in Four Radar Domains of Northeast Brazil

International Journal of Climatology, EarlyView.
This study analyzes the climatology and evaluates how the physical aspects of precipitating systems are influenced by the dry and wet seasons in Northeast Brazil, highlighting seasonal variations in the frequency, size, intensity, and duration of these systems in the regions of Natal, Maceió, Petrolina, and Salvador.

The “M and P” Technique for Damage Identification in Reinforced Concrete Bridges

Infrastructures
The seismic damage in reinforced concrete bridges is identified in this study using the “M and P” hybrid technique initially developed for planar frames, where M signifies “Monitoring” and P denotes “Pushover analysis”.

Sunshine Duration in Brazil From Meteosat (1983–2020): Climatology, Variability and Long‐Term Trends

International Journal of Climatology, EarlyView.
Using nearly four decades of Meteosat satellite data (1983–2020), this study presents a country‐wide climatology of sunshine duration (SDU) in Brazil. The results reveal marked regional contrasts, dominant modes of variability, and significant long‐term trends, providing new information on the most relevant meteorological systems that influence SDU and

Seismic assessment of existing reinforced-concrete arch bridges

Građevinar, 2014
A new seismic assessment procedure for arch bridges is presented in the paper. The linear response spectrum analysis and the nonlinear static pushover methods are combined in this procedure through various assessment levels and appropriate checks ...

Variability of the Climate in Athens‐Greece Over the Last 165 Years of the Period 1858–2023: An Assessment Based on Thornthwaite's Climate Classification and Relevant Indices

International Journal of Climatology, EarlyView.
Athens' climate according to Thorthwaite is stable despite warming trends. Athens' climate remains semi‐arid and mesothermal over 165 years. Strong increases in evapotranspiration and stable precipitation were found. Soil water storage capacity affects water deficits but not aridity type.

Analytical comparison between seismic performance of middle-rise bundled tube and 3d moment frame structures [PDF]

پژوهش‌های زیرساخت‌های عمرانی, 2019
In this study, the performance of resistant skeleton of mid-rise moment frames under scaled near-field earthquake records have been evaluated by using both, incremental dynamic and nonlinear dynamic time history analyses.

Projected Intensification of Hydroclimatic Extremes in Rio Grande do Norte, Brazil, Under CMIP6 Scenarios

International Journal of Climatology, EarlyView.
The graphical abstract presents observed (1963–2023) and projected changes in hydroclimatic extremes in Rio Grande do Norte, Brazil. It integrates dry‐spell duration (CDD) and extreme precipitation (R95pTOT) using CMIP6 multimodel ensembles under SSP1‐2.6, SSP2‐4.5, and SSP5‐8.5.

Evaluation of a Simplified Method to Estimate the Peak Inter-Story Drift Ratio of Steel Frames with Hysteretic Dampers

Applied Sciences, 2017
In this paper, a simplified method is proposed to estimate the peak inter-story drift ratios of steel frames with hysteretic dampers. The simplified method involved the following: (1) the inelastic spectral displacement is estimated using a single-degree-
