ABSTRACT Steel Concentrically Braced Frames (CBFs) are widely used in seismic regions, with chevron and split‐X configurations commonly adopted for their structural efficiency and architectural flexibility. Although extensive research has been carried out on these systems, the effectiveness of the formulations available in the literature for estimating

ABSTRACT Considering the needs for reducing carbon emissions and except for extreme cases of very degraded existing structures, research on technologies allowing continued use or upgrading of older buildings has become a priority topic. Generally, research on upgrading of reinforced concrete frame structures certainly has a prominent role, because of ...

ABSTRACT Retaining walls are key geotechnical components of road infrastructure, whose seismic performance directly affects the resilience of transportation networks. Despite their importance, seismic fragility models for retaining walls available in the literature refer only to specific case studies.

A Comparative Analysis of Multistory Building Seismic Analysis in Various Seismic Zones
Given the limited area available and the increasing population, multi-story structures are designed to house large numbers of people in cramped quarters. Construction of multi-story structures for residential and commercial purposes became necessary as a result of the population increase and the industrial revolution, which led to a migration of people

Complex Versus Parsimonious Site‐Based Stochastic Ground Motion Models: Which One Is Better?
ABSTRACT Stochastic ground motion models (GMMs) provide a probabilistic representation of seismic input and are increasingly important for uncertainty quantification (UQ) in earthquake engineering. This study focuses on site‐based stochastic GMMs, which learn the statistical features of selected datasets of seismic records and generate statistically ...

Time‐Variant Seismic Fragility of Reinforced Concrete Bridge Piers Considering Degradation Phenomena
ABSTRACT Aging and environmental exposure progressively deteriorate the physical and mechanical properties of construction materials, thereby affecting the safety and functionality of existing infrastructure. Corrosion of steel rebars in reinforced concrete structures is widely acknowledged as the most common and detrimental degradation phenomenon, as ...

Directionality Scaling of Scalar and Vector Ground Motion Intensity Measures
ABSTRACT The azimuthal directionality of earthquake ground‐motion intensity measures (IMs) is conventionally described by the ratios between the orientation‐independent maximum (RotD100) and median (RotD50) values over the horizontal plane. This study presents a refined characterization of the directionality of 31 IMs, including spectral accelerations (

Seismic vulnerability of Yazd [PDF]
Occurring earthquake in Iran plateau is common due to that Iran is on seismic belt and having a large number of faults. Studying of Yazd’s vulnerability in Iranian’s seismic code earthquake is the goal of this research.

ABSTRACT In current dynamic time history assessment protocols, ground motion recordings are mostly oriented along fixed sensor directions. Consequently, the orientation of the principal resultant of rupture energy, which may control the maximum structural demand, remains undefined, precluding consistent correlation with physically detrimental ...
