Abstract
Ovaj rad proučava učinak prostorno promjenjive potresne pobude oslonaca na odziv grednog mosta. Po važećoj normi u konstrukterstvu [3] ovaj učinak je potrebno razmatrati samo kod mostova duljine veće od 400 m ili kod mostova s nejednolikim uvjetima temeljenja. Upitno je jeli opravdana ovakva odredba, te se aktualno provode istraživački radovi koji preispituju njenu opravdanost [7]. Kroz ovaj rad će se izložiti dio metodologije koja se koristi u ovakvim istraživanjima. Numerički proračuni direktne integracije, pomoću metode stanja prostora i pomoću metode centralnih konačnih razlika, su razvijeni u programskom jeziku Python. Građevinski fakultet u Rijeci posjeduje dva stola za potresnu simulaciju čime je moguća usporedba numerički dobivenih rezultata i eksperimentalno dobivenih rezultata. Prilikom provođenja takvih usporedba naišlo se na nekoliko problema s korištenom opremom, tako da se u ovome radu daje prikaz usporedbe rezultata za samo jedan eksperiment. U rad je uključen i prikaz utjecaja različitih kašnjenja potresnog signala na pomake grede. Daljnja istraživanja na ovome području su svakako poželjna. Napredak postojećih saznanja o utjecaju prostorne promjenjivosti potresne pobude bi doveo do sigurnijih i ekonomski opravdanih konstrukcija mostova.
Abstract (english)
The effect of spatially variable support excitation on seismic response of beam is considered. Eurocode 8 recommends that such an effect is considered only for bridges longer than 400 m or for bridges with significantly varying foundation soil conditions [3]. Such a restriction is potentially questionable and research on its justification is being carried out [7]. Some of the numerical methods used for simulating spatially variable support excitation are described here - methods such as direct integration by the state space method and by the central finite difference method. Both of them are implemented using the programming language Python. Faculty of Civil Engineering at Rijeka houses two shaking tables used for earthquake simulation and with this setup a comparison between the numerical and experimental results is possible. Work on this comparison was hindered by a few operational setbacks with the equipment, hence the comparison is given for a single experiment only. Sensitivity study on the effect of the time delay of the earthquake signal between two supports on the bridge displacements is also included. Further research in this field is definitely desired. Better understanding of the spatially variable support excitation and its significance in structural design could lead to more economical and safer bridges.
