| Popis: | Studija je izrađena kako bi se ostvarila tri cilja: (1) usporedba neelastičnih odziva građevina na bliske i udaljene pobude, (2) istraživanje utjecaja odnosa impulsnoga perioda i perioda konstrukcije te (3) ocjena niza mjerenja intenziteta (IM) za bliske potrese. Postojeća armiranobetonska zgrada s 35 katova analizira se u okviru prvoga i drugoga cilja, dok se u okviru trećega cilja analiziraju tri okvirne građevine s po 6, 13 i 20 katova. Rezultati pokazuju da kod bliske pobude može na građevinama doći do prekoračenja razine sposobnosti zaštite života. Osim toga, točnost mjerenja intenziteta u velikoj mjeri ovisi o periodu titranja građevine i o funkciji koja se rabi za izračunavanje vrijednosti IM. This study is presented to achieve three objectives: (1) to compare between the inelastic responses of buildings under near and far fault excitations, (2) to investigate the effect of the pulse to structural period ratio, and (3) to evaluate a set of intensity measurements (IMs) in terms of near fault (NF) earthquakes. A real reinforced concrete building with 35 storeys is analysed in the scope of the first and second objectives, whereas the third objective involves three general-frame buildings consisting of 6, 13, and 20 storeys. Results show that the NF excitation can drive the building to exceed its life safety performance level. Furthermore, the accuracy of the IM highly depends on the vibration period of the building and the function used to calculate the IM. |
