In this work, the actual operating conditions of a walking beam and direct flame reheating furnace for conventional steel slabs in continuous motion were numerically simulated. The fluid dynamics, heat transfer, chemical species combustion solved coupled way using readaptation computational domain by means dynamic mesh. results validated temperature measurements averaged over 24 hours plant operation with 16 thermocouples, resulting an average error 2.56%. With reduction flow rates range...
This paper presents the results of a multifaceted investigation into vortex-induced vibrations stay cables roundabout flyover. Large cable were spotted during moderate wind speed conditions immediately after completion structure, and three weeks, because concerns about structural integrity system, temporary restrainers applied. An was conducted to assess potential fatigue damage that occurred time, combining experimental measurements finite-element model system. As result, sockets replaced,...
This paper deals with the experimental investigations carried out on a cable-stayed pedestrian and bicycle bridge.Shortly after installation of bridge, it turned that cables vibrated in wind.Experimental were soon started to determine exact cause vibrations aim finding definitive solution.Vortex shedding was found Stockbridge damper mounted test its effectiveness.A case vortex induced also measured together wind speed site as confirmation study.Finally, prediction number cycles suffered by...
Currently, the energy and environmental efficiency of buildings has led to development cladding systems that may help reduce structure’s demand, using techniques such as Permeable Double Skin Façade (PDSF). Given complex aerodynamic interactions, presence an external porous screen in addition inner skin play a crucial role fluid-dynamic characterization buildings, making definition wind effects very complex. A new methodology for quantitative assessment impact wind-loading conditions on this...
This paper examines the aerodynamic properties of a rectangular tall building with sharp edges. The has section aspect ratio B/D = 2.6 and height H/D 9, giving in quite slender prismatic configuration. study was performed on sectional three-dimensional models building. model tested smooth flow condition, coefficients were determined. Forces pressure distributions measured to compare behavior model. Both rigid (non-moving) moving analyze possible aeroelastic effects. Different levels incoming...
This paper describes wind tunnel tests performed on models of the Talavera de la Reina cable stayed bridge. The work aeroelastic model construction and it is focused evaluation analysis mean peak loads at tower foundation anchorages since these data can be very useful by bridge manufacturer as a support for design. part complete study carried out to analyze stability
The paper presents the results of modal parameters identification and continuous monitoring two arches built in new area Expo 2015 Milan. activities on were performed during erection stage they planned as a consequence preliminary studies at Politecnico di Milano wind tunnel, that highlighted dynamic instability due to wind. In particular, first bending modes structures showed critical behaviour for this reason TMD (Tuned Mass Damping) system was designed order control these modes. At first,...
The presented paper deals with the structural identification and monitoring of two twin chimneys in very close arrangement. Due to arrangement, important interference effects are expected modify chimney response wind action, causing vortex shedding state-dependent excitation associated oscillatory motion leeward chimney, out windward wake. complexity physics this problem is increased by dependency aerodynamics circular cylinders on Reynolds number; however, there a weakness literature about...
Os acidentes de transporte terrestre são uma das principais causas mortalidade global, especialmente entre jovens e adultos, causam impactos significativos em áreas essenciais como saúde economia. Este estudo visa comparar selecionar um modelo para classificar as rodovias federais Minas Gerais, Brasil, utilizando métodos tratamento dados técnicas Machine Learning. Dados da Polícia Rodoviária Federal, 01/01/2023 a 30/09/2023, foram usados analisar os algoritmos Random Forest (RF), Support...
