• Description:
  This project was concerned with measuring the loads and behavior of temporary support structures that are used in the construction of reinforced concrete buildings. The main features of this work included: (1) measuring and horizontal shoring loads at four sites--a federal prison in Beckley, West Virginia, a library storage facility on East Ave. on the University of Vermont campus, a reconstructed old building (Pomeroy Hall) on the University of Vermont campus, and a 25-story building referred to as the Boston Museum Towers; (2) Measurement of shore load effects including load sequence effects, soft footing effects, and lateral instabilities in the laboratory; (3) A detailed mechanical and reliability analysis of shoring systems using both the simplified and modified simplified techniques that account for elasticity and creep; and (4) A comparison of the measured loads with those specified by the design codes. The field studies and the code comparisons resulted in a set of tentative recommendations for construction practice and a refinement of the codes. The laboratory studies concluded that shore loads are highly sensitive to member length variations, soft footings, and load applications sequences. Symmetric load applications result in smaller member loads by about 20 percent. The laboratory experiments also indicated that shore member tilt can be used as a precursor warning measurement for lateral instabilities. [Description provided by NIOSH]
