Rehabilitation projects or projects with special construction issues can be overwhelming, especially if they have an irregular shape such as flare, taper, and joining girders.For existing bridges, it is essential to evaluate live load together with staged construction analysis appropriately. For existing bridge evaluation for live load and staging, engineers must be able to review details like truck locations and concurrent results during or after staged construction analysis. In this case, not only unique staged construction steps, but also convoluted live load cases with special sequence are necessary.
Therefore, rehabilitation and other special projects that involve existing aged structures require software that has user-oriented modeling capabilities, provides options in a sense that user can set up complex staged construction and live load cases together with efficiency, and produce accurate and practical analysis results such as concurrent forces and the position of a vehicle at the critical situation.
