Analysis and design of short reinforced-concrete columns

U radu je dan prikaz proračuna i konstruiranja kratkih stupova, sličan onomu za vezne grede zidova s otvorima, dominantno naprezanih poprečnim silama. Opisana su istraživanja o ponašanju nosivosti kratkih stupova koja su poslužila za novi prijedlog proračuna. Po ovom postupku primjenjuju se bidijagonalni koševi čeličnih šipki, kako bi se osigurala dostatna nosivost i duktilnost pod djelovanjem potresa, pri kojem se mogu očekivati tolerantna i lako popravljiva oštećenja betona.The analysis and design of short columns, similar to that of tie beams for walls with openings, dominantly subjected to transverse forces, is presented in the paper. Historic studies of load behaviour of short columns, as used in development of the new analytic procedure, are described. In this new procedure, bi-diagonal steel-bar cages are used to ensure a sufficient bearing capacity and ductility under earthquake action, at which tolerable and easily remediable damage to concrete may be expected
