BUCKLING ANALYSIS OF HORIZONTALLY ELASTICALLY-SUPPORTED ARCHES |
|
| Abstract: | It was studied the bucklings of horizontally elastically supported arches,and the linear analytic results of the horizontally elastically-supported arches under three loads were also presented.The symmetrical and antisym-metrical bucklings of such arches were analyzed,and a demarcation between the symmetrical buckling and antisymmetrical one was got.The formula for calculating the critical axial force as well as the recommendations on design were put forward. |
| Keywords: | arch buckling linear analysis elastic support axial force |
