Short Note on Calendar Hamilton span

Calendar Hamilton span

• The modern day pref abricated Panel/Floor Beam/Deck system was first patented by A.M. Hamilton in 1935

• The bridge was used or quick mobilization to allow military access to remote locations or to replace destroyed bridges in times of conf lict.

• The design was centered on a series of gusset plates that allowed the direct attachment of the longitudinal, diagonal, vertical, and cross framing members.

• The centralizing of connection points increased the speed of construction and also allowed identical panels to be fabricated from identical members and then installed on site

• This system is currently known as the Calendar- Hamilton System.

• Calendar Hamilton Spans are designed for the purpose of building long spans as rapidly as possible to us in place of standard spans damaged due to accidents, floods or enemy action.

• This also used in case of washed away of multiple spans and there is no chance of erecting the temporary substructure in the river bed.
