摘要:
将单箱多室波形钢腹板箱梁等效为平面板梁模型,用刚接梁法推导了单箱多室波形钢腹板箱梁荷载横向分布系数的计算公式,并对1根单箱双室波形钢腹板箱梁进行了荷载横向分布试验研究.研究结果表明,刚接梁法计算结果与试验及有限元结果的误差均小于7%,与考虑中横隔板的有限元结果相比,偏于安全.对于有、无中横隔板的单箱多室波形钢腹板箱梁,均可采用刚接梁法计算其荷载横向分布.根据试验结果建议单箱双室波形钢腹板箱梁荷载横向分布系数沿桥跨的取值为:弯矩可统一采用横向分布系数mc(mc为刚接梁法计算的跨中荷载横向分布系数);中梁支反力在梁端采用0.6m0(m0为杠杆原理法计算的梁端荷载横向分布系数),L/4~L区段内采用mc,梁端至L/4区段,呈直线形过渡;边梁支反力可统一采用0.9m0.
Abstract:
A formula for calculating the load transverse distribution coefficient of single box multi-cell girder with corrugated steel webs was deduced by the rigid connected beam method on the basis of the equivalent plane plate-girder model. Then, a test on a single box double-cell girder with corrugated steel webs was carried out to research its load transverse distribution. The research results show that the error between the load transverse distribution coefficient calculating with rigid connected beam method and that obtained from test and finite element analysis is less than 7%. Compared with the finite element analysis result of the girder with midspan diaphragm, the load transverse distribution coefficient calculated by the rigid connected beam method is relatively safe. Thus the rigid connected beam method can be used to calculate the load transverse distribution coefficient of the single box double-cell girder with corrugated steel webs where or not there is a diaphragm in the midspan of the girder. The distribution law of the load transverse distribution coefficient along the longitudinal of single box multi-cell girder with corrugated steel webs was suggested according to the experimental results.The moment transverse distribution coefficients are mc, where mc is the load transverse distribution coefficient at the middle span calculated by the rigid beam method. For the support reaction transverse distribution coefficients of the middle girder, 0.6m0 is used at the end, where m0 is the load transverse distribution coefficient at the end calculated by the level principle method; mc is applicable from L/4 to L; and the transition from the end to L/4 is linear. The support reaction transverse distribution coefficients of the side girder are 0.9m0.
