| Abstract: | The technical characteristics and the problems of design and construction of steel inclined arch on concrete column are discussed. Important difference between arch and beam,sensitivity of thrust release and variability of arch moment affected by roof slope,displacement of arch apex affected by displacement of arch thrust,possibility of changing arch into beam,suitable details of arch thrust,necessary construction method to diminish release of thrust etc have been mentioned. It may be served as a reference ... |
