• who: from the Maximum spacing and stud spacing limits in design specifications The current AASHTO maximum spacing requirement of , in(609., mm) first appeared in , in the fourth edition of the Standard Specifications for Highway Bridges [9]. At the University of Illinois Chicago, a composite design study for the Public Roads Administration was carried out. The investigators performed quarter-scale model tests on composite bridges and recommended a maximum spacing of three to four times the slab depth because of possible separation between the slab and the steel girders. The sample bridge had a slab thickness of . . .
