Analisis Kekuatan Pelat Lantai Dermaga di Pelabuhan Ciwandan Banten Terhadap Penambahan BMC

Abstrak

Pier 005B is located at Pelabuhan Indonesia II (Persero) Branch of Banten and has a length of 300
meters and a width of 44 meters. It is planned that at Pier 005B, will be putted 1 (one) unit of Harbor Mobile
Crane (HMC) brand LHM 420 will be placed as a supporting tool for loading and unloading activities from and
to ships. This HMC certainly has certain specifications and capacities, so it must be calculated properly against
the additional load that can be accepted by the floor slab of Pier 005B. The research method used is descriptive
qualitative. This HMC is capable of carrying a maximum load of 124 tons at a distance of 12 to 16 meters. With
the HMC's own weight of 371 tons and the assumption of a human weight of 0.4 tons/meter2, the total weight of
HMC received by the floor slab is 22.68 tons/meter2. By using the SAP 2000 version 22 computer application,
the ultimate internal forces due to the load on the floor slab are the ultimate moment of 7.27 ton.meter, the
ultimate shearing force of 7.61 tons and the limit of deflection of 7.17 mm. Then re-calculated the capacity of
the existing floor slab in accordance with the Indonesian National Standard (SNI), obtained the internal forces
that can be borne by the floor slab, namely the slab moment of 18.49 ton.meter, plate shear force of 22.38 ton
and the deflection limit. plate by 14.58 mm. So it can be concluded that the floor slab of Pier 005B is capable of
carrying the Harbor Mobile Crane (HMC) load.
