COMPOSITE ACTION CRUCIAL FOR RENOVATION. LRFD - THE QUIET REVOLUTION

The article describes how more than 4,000 square feet of floor area was brought up to required strength with the addition of 550 slab ties and 55 shear studs. In this project for the strengthening of a floor carrying heavy medical diagnostic equipment, the efficiency of load and resistance factor design (LRFD) in analyzing composite construction proved crucial during the renovation. The use of LRFD led to the use of a sophisticated and innovative though simple solution to the problems of the construction. The full composite strength of the flooring system, which is available in the LRFD code, could only be obtained by adding shear studs (55) to the existing girders. Also, the two slabs needed to be tied together with shear pins to take advantage of the full composite strength of the floor.
