REVIEW OF RELATED LITERATURE
This chapter presents the studies and literature that the researchers used to support the
importance of the current investigation. The process, equations, and steps required to understand the
subject clearly are also provided.

The wooden bridge was continuously saturated with seawater, exposed to heat and rain, and
managed by NHA's general manager, Marcelino P. Escalada Jr. "That is a wooden footbridge that has
been immersed in seawater and exposed to the elements. He added that aside from being "a footbridge
for humans, it is also utilized by tricycles," and that it can quickly decay 300 times quicker than any other
wooden bridge. He also stated that "just like any other bridge, whether it's steel, suspended, or concrete
bridge, may load limit siya." Even more so, considering the footbridge. Maybe the weight used to
support the bridge wasn't running, moving weight (National Housing Authority, 2018). In constructing a
footbridge, not only the specifications are included, materials and the design of the bridge itself, but also
other factors must be included such as the ambiance that affects the load of the footbridge like the
water with such elements and the geological elements of the soil that holds the columns of the bridge.

The best alternative for spans of 10 to 20 meters, and maybe up to 25 meters, where it is not
feasible to build piers for intermediate supports for beam type footbridges, is a steel truss footbridge.
When piers are an option, it should also be considered for spans over 10 meters (DESIGN OF STEEL
TRUSS FOOTBRIDGE, n.d.). When beam types of footbridge reaches a very long span, there is a chance
