To liberation, the two piers cracks have occurred, endangering the bridge itself, has had to limit heavy vehicles crossing the bridge, speed limits, limit the number. 1954, the local spent six months repaired the crack of the pier, in the original steel trusses on the level of amputation and a curved shape of the upper limbs, using reinforced concrete bridge deck boards, so that the bridge deck beam into a combination of vertical and horizontal beams, Increase the carrying capacity of 20 tons of cars can have full. 1981, the upper reaches of the Yellow River Bridge has withstood the test of catastrophic flood, safe and sound.

到解放时，两个桥墩已发生裂缝，危及大桥本身，不得不对过桥车辆限重、限速、限数。1954年，当地用了半年时间修好了开裂的桥墩，在原来钢桁架的水平肢上加了一根弯曲形的上肢，桥面改用钢筋混凝土板，使桥面的纵横梁变为组合梁，提高了承载能力，20吨重的汽车可以畅行无阻。1981年，大桥经受了黄河上游特大洪水的考验，安然无恙。

The finite element model included two types of main element: beam element for concrete and truss element for internal unbonded or external tendon. The end nodes of main elements were connected with internal constraints named MPC in ABAQUS. Spring elements with very large stiffness were set up at the place of the deviators of externally prestressed beams, or along the span with relatively little space of unbonded internally prestressed beams. The modified Riks method is utilized to trace the entire structural response of beams prestressed with unbonded tendon from zero to ultimate loads. The reliability of the analysis model is verified by analytical results of typical test beams in comparison with experimental ones.

该有限元模型由两类主单元组成，即混凝土梁单元和体内无粘结或体外预应力筋桁架单元；主单元的端部节点用ABAQUS的内在约束MPC连接；在体外预应力梁的转向块处，或沿体内无粘结预应力梁全跨并以比较小的间隔设置刚度足够大的弹簧单元。

The overpass at You'ai Road in Nanning is located at the traffic junction of the city, congested as it is and the prestressed concrete continuous box girder of the main bridge with in-situ scaffold construction can not meet the traffic needs The adoption of box girder in-situ scaffold combined with Bailey truss and universal rod, which is of long span, large rigidity and little deformation, meets the traffic needs Meanwhile the rapid combination of scaffold overcomes the shortcomings of high scaffold and ...

根据南宁市友爱路立交桥位于城市交通咽喉，车辆拥挤，主桥预应力砼连续箱梁现浇支架施工难以解决交通需求的矛盾，采用了贝雷桁架与万能杆件组合拼装箱梁现浇支架，该支架跨度大、刚度大、变形少，不仅解决了交通需要，而且支架拼装速度快，同时也解决了支架高、稳定性差的缺点。这一施工技术可在日益发展的城市立交桥施工中得到广泛使用。

Inclined column transfer is a new transfer structure,which can been seen as the combination of truss transfer and beam transfer,also can been named by local truss transfer.

斜柱转换是近年来出现的一种新的转换形式，它可以看成是桁架转换和梁式转换的结合，也可称为局部桁架转换，其在实际工程中得到较为广泛的应用。
