| Abstract: | After the simplification of the spatial structure of Dai He Bridge due to its symmetrical characteristic,the analytical solutions to the concrete-filled steel tubular arch bridge are obtained by calculation.And then after checking the stress on the critical cross section,the security of the key sections is testified by comparing with the admissible values.Finally,a general pattern of the simplified calculation of the concrete-filled steel-tabular tie-bar arch is put forward to give reference to the manual c... |
