<p>The present invention relates to a shear resistant beam in buildings which consists of upper and lower longitudinal reinforcements (2), diagonal tension reinforcements (4) and connecting plates (3). The tension reinforcements (4) are knotted in the form of intersection of the upper and lower longitudinal reinforcements (2). Each intersecting point is fixed by welding to form a "X"-type frame structure. Based on the required thickness, the frames are welded to a whole shear resistant beam by use of transverse straight reinforcements (1). The connecting plates 3 are welded at the ends of the shear resistant beam. The shear resistant beam and the building structure are connected through the connecting plates by bolts. The shear resistant beam is simple in fabricating technology, its rigidity, shear resistance can be increased by more than two times, and the costs can be reduced and 10 per cent of steel material can be saved. <IMAGE></p> |
