The main load-bearing structure of the bridge is a hole L0=36 m reinforced concrete arch, with a total width of 3.4 meters, the highest to the lowest level of 17 meters, the use of bowl buckle scaffolding, scaffolding longitudinal 0.6m, transverse 0.9m, step 1.2m. Help me to calculate the bearing capacity of ah thank you!
The first layer of wood even finished the calculationThen go down and check it outThe second layer is the fulcrum of wood 90cmFinally, according to the reaction force of the fulcrum to the maximum force on the rod to judge whether the rod can meet the requirementsAccording to 1.2 of the bowl buckle bracket of 18 meters maximum can only withstand the force of 35KN
Fulcrum spacing is 60cm longitudinal timbers, fulcrum M, square distance is W then according to uniform load distribution Q=p/wThen according to the number of cross W-1 span continuous beams with calculated Pmax and MmaxIn the calculation of I, W, E the final Mmax/W< limit stress but also to calculate the degree of winding </1400L (I value according to the size of the calculation, i=bh^2/6)The first layer of wood even finished the calculationThen go down and check it outThe second layer is the fulcrum of wood 90cm
Assuming that the web is N, the calculated load is P=1.2*N+1.4*n (n)That support is a layer of a layer of wood longitudinal transverseThen calculate vertical
First calculate the area of the largest section SAccording to the cross section can be found in the largest force range, such as the web is always the heaviest, the wing plate and the bottom plate is relatively light
