刚架拱的计算目前采用的是力法,由于要解一个5次(对称)和4次(反对称)超静定,其系数又得采用繁杂的图乘法计算,从而其计算工作量较大,不便为生产部门所采用。文献提出了混合法,对刚架拱的计算有所改进,但改进的不多,因为采用这一方法时,在对称荷载下仍要解一个5次超静定,在反对称荷载下要解一个4次超静定,结果与力法相同,仅改进了系数的计算。 刚架拱有一定的优点,目前为生产部门采用的较多,因而迫切希望能有一种适合手
The calculation of rigid frame arch is currently using the force method, due to the solution of a 5 (symmetric) and 4 (antisymmetric) statically indeterminate, and its coefficients have to use complex graph multiplication calculation, so its computational workload , Inconvenience used by the production department. The literature proposes a hybrid method that improves the calculation of rigid-frame arch but does not improve much since this method still has to be solved for a fifth instability under symmetrical load and under antisymmetric load A 4 times statically indeterminate, the same result with the force method, only to improve the calculation of the coefficient. Rigid arch has some advantages, currently used by the production sector more, so eager to have a suitable hand
