The development of floating bridges is a major engineering challenge to make the existing bridges durable and easy to construct. The connection pontoon unit between the heavy communication bridge (HCB) and the assault bridge (AB-PMM71) is discussed as developed by Mazek et al. [1]. The new connection pontoon (NCP) should offer fast
assembly time to operate the combat floating bridge. The floating bridge system including the HCB, the AB-PMM71, and the NCP is modeled. The 3-D numerical model of the floating bridge system is proposed by the nonlinear finite element analysis under static and dynamic Military load Class MLC70. The field test for the new floating bridge system was conducted by [1]. The proposed finite element model of the floating bridge system is verified based on the practical field test developed by [1]. The numerical results have good agreement with those obtained by the reviewed field test.
