Design Example <br /> The following design example illustrates an application which utilizes the SmartJack® system to provide <br /> supplemental support of an existing span of floor joists which are not supporting any load bearing walls or <br /> columns.The Smart-lack system may also be used to provide supplemental support of existing beams and girders, <br /> but the evaluation of the loads involved is more complex than can be addressed in this design example. <br /> Existing Span <br /> I I <br /> I i <br /> I <br /> Su lemental Floor Joist V <br /> Beam Varies Main------ <br /> Girder I <br /> I <br /> ® System Height Varies <br /> SmartJack System <br /> Foundation Interior <br /> \/\\/\\ I•: .
