Performance of tall buildings in Concepción during the 27 February 2010 moment magnitude 8.8 offshore Maule, Chile earthquake

Abstract

Artículo de publicación ISIConcepción, near the southern end of the fault rupture zone of the offshore Maule, Chile earthquake, suffered signifi cant damage to all types of structures. Tall reinforced concrete buildings in the region were also affected, some severely. Spectacular collapse and partial collapse were experienced in two buildings, and many buildings had failure of thin shear walls that lacked suffi cient boundary element confi nement. Concrete spalling and crushing occurred and reinforcing steel buckled and were sometimes fractured

Utjecaj potresnih zona i lokalnih uvjeta tla na odziv armiranobetonskih zgrada

“…Nedavni potresi, poput onoga koji je 1999. pogodio Kocaeli ., također su uzrokovali ljudske žrtve i goleme materijalne štete. Brojni znanstvenici su analizirali štetu koju su potresi prouzročili na zgradama, te prenijeli naučeno iz takvih prirodnih katastrofa [1][2][3][4][5][6][7][8][9]. Značajna potresna aktivnost i lokalni uvjeti u tlu u velikoj mjeri utječu na stupanj oštećenja zgrada [10,11].…”

Study of structural capacity and serviceability affecting the obstruction of residential door

“…In recent times, the seismic activity recorded in Chile has attracted scientific interest within a number of areas of engineering sciences , particularly in identifying the causes that have triggered diverse damages in residential buildings, as well as the development of structural evaluation systems (Rojas et al, 2010). This interest has grown much more after the last earthquake on February 27 in the central-southern Chile, whose magnitude reached 8.8 on the Richter scale (Lay et al, 2010).…”

Experimental Study on Behaviors of Adaptive-slit Shear Walls

“…Fig. (1) shows some typical examples of tall walls failed in shear after strong earthquakes [6,16,17].…”

“…When the horizontal load was further increased, many short minor cracks along the cold-formed thin-walled steel were observed and vertical macro-cracks formed. The width of diagonal crack is very small before the peak load, and the relative deformation of (a) A failed wall in Kalamat earthquake in 1986 [16] (b) A failed wall in Wenchuan earthquake in 2008 [6] (c) A failed wall in Chile earthquake in 2010 [17] Fig .
