Sudaranje objekata visokogradnje tokom dejstva zemljotresa

Abstract

Savremeni propisi i praksa u projektovanju objekata visokogradnja ne razmatraju u dovoljnoj meri mogućnost da dođe do sudara međusobno bliskih objekata tokom dejstva zemljotresa. U radu je dat kratak osvrt na dosada zabeležene slučajeve sudaranja objekata i analiza nastale štete. Nakon toga, prikazane su metode analize sudaranja dva bliska objekta. Te metode se mogu podeliti grubo na 2D i 3D analize. Date su pretpostavke sa kojima se ulazi u analizu, matematički opis problema, analitička i numerička rešenja. Date su neke smernice za numeričko modeliranje problema i analizu dobijenih rezultata. Izvršen je pregled seizmičkih propisa i aktuelnih istraživanja vezanih za temu sudaranja objekata. Kao zaključak, date su smernice za moguća dalja istraživanja.

Contemporary codes and practice in building design do not take adequately as an option pounding and collision of adjacent buildings during earthquake. A brief overview of historic data related to pounding of building and recorded damage is given. After that, methods for building pounding analyses are presented. Those methods can roughly be divided into two groups, 2D and 3D analyses. For both methods, basic assumptions for analysis, the mathematical description, analytical and numerical solutions are presented. Guidelines for numerical analysis and interpretation of obtained results are given. An overview of seismic codes and current research related to building pounding analysis is given. As conclusion, guidelines for future research are given.
