On Wednesday, Mar. 15, from 9:30-10:15 a.m., in West Hall, Room 203-205, Walsh will present “Lifting Load Effects on Elevated Structures” as part of ConExpo’s educational program.

The educational session will cover the effects that lifting and moving of loads has on elevated structures, decks, bridges, and underground facilities like utilities, vaults, and foundations.

It will look at host structure stability and integrity during crane and gantry lifts, as well as during horizontal movement by SPMTs, slide jacking, and other devices.

Specific topics Walsh will cover include: basic forces; types of loads generated; awareness, identification, and documentation of as-is conditions; ways to mitigate load effects.
