Title: Performance of a Press-Lam bridge : a 5-year load-testing and monitoring program

Author: Gromala, D. S.; Moody, R. C.; Sprinkel, M. M.;

Date: 1985

Source: (Research note FPL ; 0251):7 p. : ill ; 28 cm.

Publication Series: Research Note (RN)

Description: This paper summarizes the results of load tests on an experimental highway bridge erected and put into service on the George Washington National Forest in Virginia in 1977. The bridge, made entirely of Press-Lam, a laminated veneer lumber (LVL) product, was load tested 1 month, 1 year, and 5 years after erection. The bridge continues to perform quite well and, although a slight increase in bridge flexibility was noted during this time period, the deflections were well below those calculated in the original design. Thus, laminated veneer structural members can be successfully used in exterior structures.
