Seismic Assessment Procedure for Exterior Reinforced Concrete Beam–Column Joints With Slab and Transverse Beams

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This article presents a capacity‐based assessment procedure for beam–column (b–c) joints of reinforced concrete frames with floor slabs and transverse beams. The procedure extends a previously proposed assessment methodology for determining the hierarchy of strengths and the sequence of events in symmetrically reinforced planar b–c joints.

A Study on the Effects of Punch-to-Span Ratio and Longitudinal Reinforcement Eigenvalues on the Bearing Capacity of RC Slab–Column Connections

Buildings
The region of the RC slab–column connection is subject to complex forces and is susceptible to localized damage, leading to progressive collapse incidents, which has raised considerable concern among the engineering community. At present, the research on

Prediction of Punching Capacity of Slab-Column Connections without Transverse Reinforcement Based on a Backpropagation Neural Network

Advances in Civil Engineering, 2019
Punching shear failure of slab-column connections can cause the progressive collapse of a structure. In this study, a punching test database is first established.

Dielectric Resonator Metasurface for Dispersion Engineering

, 2016
We introduce a practical dielectric metasurface design for microwave frequencies. The metasurface is made of an array of dielectric resonators held together by dielectric connections thus avoiding the need of a mechanical support in the form of a ...

Late Quaternary climatic variability in the Eastern Mediterranean recorded in Hermes Cave, Corinth Rift, Greece

Journal of Quaternary Science, EarlyView.
ABSTRACT The Greek peninsula lies at the intersection of major atmospheric circulation systems, making it a key location for reconstructing past climate variability in the Eastern Mediterranean. In this study, we present a new high‐resolution multi‐proxy speleothem record from Hermes Cave, located on the shoulder of the Corinth Rift in southern Greece.

Punching shear in flat slabs with re-entrant corner columns [PDF]

Revista IBRACON de Estruturas e Materiais
Studies on slab-column connections supported on re-entrant corners are limited. Although design standards generally provide detailed guidelines for internal, edge, and corner connections, re-entrant corner connections are overlooked in these standards ...
