As shown in Figure 1, Figure 2, a kind of structure promoting combination beam performance, including crossbeam and in I-shaped girder steel.It is horizontal
The length direction of beam is horizontal direction, and the top of girder steel is along the inside of horizontal direction stemple, and crossbeam is by reinforced concrete
Soil is made.Multiple dampers are equipped on the lower face of crossbeam and girder steel；Damper includes two bearings and damper assembly, damping
One end of component is connected on a bearing, and the other end of damper assembly is connected on another bearing.
In conjunction with shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, in I-shaped girder steel include integrally formed upper steel plate, junction steel plate,
Lower steel plate；The upper end of junction steel plate and the centre of upper steel plate connect, the lower end of junction steel plate and the centre of lower steel plate
Connection, the inside on the top and upper steel plate stemple of junction steel plate, i.e. upper steel plate are located at the inside of crossbeam, the company being vertically arranged
The top for connecing steel plate also is located at the inside of crossbeam.When making crossbeam and girder steel, crossbeam use pours mode and is made, and is pouring
When building, the top of girder steel is placed just at the inside of not yet manufactured crossbeam, in this way after the completion of pouring, the top of girder steel
Then it is located at the inside of crossbeam.The top of girder steel is located at the mode of the inside of crossbeam, improves the globality of crossbeam and girder steel.Tradition
It is to be linked together by shear connector between crossbeam and girder steel, traditional crossbeam and girder steel are also the relationship being fixed to each other,
But since there are shear connectors between traditional crossbeam and girder steel so that the globality of traditional crossbeam and girder steel is poor.
The upper surface of upper steel plate is equipped with multiple vertical pegs, and multiple vertical pegs are distributed along rectangular array, i.e., multiple perpendicular
It is uniformly distributed to peg along horizontal direction and longitudinal direction, the top of junction steel plate is equipped with multiple horizontal pegs, multiple levels
