Composite rigid-frame bridge installing prestressed compound beam to the contral point of the slab of rigid-frame bridge and connecting the beam to the steel member installed in the upper of pole

摘要

The subject innovation is a portion of the negative moment region of both ends of the columnar negative moment section with the slab of an upper end according to the load of stress acting on the rigid frame bridge is a portion of the frontal ment section of the slab to the synthesis of a steel material and concrete is prestressed composite beam to install the negative moment a portion of the negative moment interval for placing the curing, and pillar upper end the reinforced concrete after the connection with the steel material is installed in a section is a steel and concrete, and the remaining section of the pillar is to install the pole of a reinforced concrete It relates to a method of installing a composite rigid frame bridge to resist an external force such as a lateral earth pressure.; Stylized predetermined length of the composite rigid frame bridge provided by the above method columns and the slab is to be installed in the synthesis of the steel and concrete to minimize the cross-section compared to the conventional reinforced concrete cross-section reduces the dead load a predetermined period of frontal ment section of the slab is Priest because thinner than conventional reinforced concrete composite beam cross section hameuroseo install the rest there is an advantage that the area of ​​the bridge hyeongha be greatly more secure.
