In structural analyses, masonry infill walls are commonly considered to be non elements. However, the response of reinforced concrete buildings earthquake loads can substantially affected by influence walls. this article, an improved numerical model for simulation behavior subjected is proposed and analyzed. First, presented. This upgrading equivalent bi-diagonal compression strut model, used nonlinear panels cyclic loads. Second, main results calibration analyses obtained with two series...
In this study, the implementation of an optical accelerometer unit based on fiber Bragg gratings, suitable to monitor structures with frequencies up 45 Hz, is reported. The developed system was used estimate structure eigenfrequencies a steel footbridge, total length 300 m, over Sao Pedro Creek, located at University Aveiro Campus, in Portugal. acceleration records measured solution are compared those obtained by traditional commercial electronic devices, revealing root-mean-square error...
Summary One of the main challenges in earthquake risk mitigation is assessment existing buildings not designed according to modern codes and development effective techniques strengthen these structures. Particular attention should be given RC frame structures with masonry infill panels, as demonstrated by their poor performance recent earthquakes Europe. Understanding seismic behaviour masonry‐infilled frames presents one most difficult problems structural engineering. Analytical tools...
SUMMARY The cyclic behaviour of reinforced concrete columns has been the subject many experimental studies in recent years. However, most these have focused on unidirectional loading with square cross‐sections under constant axial conditions. In present study, four types full‐scale quadrangular building were tested different loading, including uniaxial and biaxial first two specimens each column type independently cyclically strong weak directions. Bidirectional tests using paths performed...
In this work we proposed a relative humidity (RH) sensor based on Bragg grating written in an optical fiber, associated with coating of organo-silica hybrid material prepared by the sol-gel method. The organo-silica-based has strong adhesion to fiber and its expansion is reversibly affected change RH values (15.0–95.0%) surrounding environment, allowing increased sensitivity (22.2 pm/%RH) durability due presence siliceous-based inorganic component. developed was tested real structure health...
A methodology aiming to predict the vulnerability of masonry structures under seismic action is presented herein. Masonry structures, among which many are cultural heritage assets, present high earthquake. Reliable simulations their response stresses exceedingly difficult because complexity structural system and anisotropic brittle behavior materials. Furthermore, majority parameters involved in problem such as material mechanical characteristics earthquake loading have a...
The cyclic behavior of reinforced concrete (RC) beam–column joints (BCJs) is still one the critical issues in structural engineering. In this context, for purpose gaining a more in-depth insight about sophisticated BCJs under loading scenarios, current work aims to investigate joints. four interior joints, with plain and deformed bars, which are representative seismically non-conforming structures from 1970s, were experimentally investigated. corresponding results specimens compared each...
