摘要： 为了准确计算考虑桥面铺装参与受力的简支梁桥横向分布系数,基于刚接梁法的基本原理,考虑了混凝土桥面铺装与主梁间存在的剪切滑移效应,采用结构力学中的基本方法提出了一种考虑桥面铺装的简支梁桥荷载横向分布系数计算方法,本文称之为修正刚接梁法。采用本文方法计算了一座实际简支T梁桥的横向分布系数,并以此计算了车辆荷载作用下各主梁的挠度和铺装层应变等静力响应,并与试验结果进行了对比分析。结果表明,计算出的静力响应与实测静力响应吻合度很高,充分说明了本文方法的准确性和可靠性。

Abstract: In order to accurately calculate the transverse distribution coefficient of simply supported beam bridge considering the effect of bridge deck pavement, based on the idea of rigid-jointed beam, a new method for calculating the transverse distribution coefficient was proposed, using the methods in structural mechanics. This method is referred as the modified rigid-jointed beam method, in which the effect of shear slip between concrete bridge deck pavement and the main girder was considered. The transverse distribution coefficient of an actual simply supported T-shaped beam bridge was calculated using the proposed method, the deflection of each main girder and the static response such as the strain of the bridge deck pavement under vehicle load were obtained and compared with experimental results. It is shown that the calculated static response is in good agreement with the measured one, which verifies the accuracy and reliability of proposed modified rigid-jointed beam method.

Key words: bridge engineering, bridge deck pavement, transverse distribution coefficient, shear slip, modified rigid-jointed beam method
