Abstract

he wharf is where the ships are moored in the harbour. In addition, the pier is also the place where loading and unloading of goods takes place and passengers boarding and falling from and to the ship. The dock is also the location for activities for refueling ships, supplying ships with drinking water, clean water, and arranging channels for dirty water/waste which will be further processed at the port. So that optimum planning is needed so that the performance of the building can meet safety and comfort standards This thesis examines conventional floor slabs and precast hollow core slabs at spans of 5.2 meters and 10.4 meters. Dead load is calculated based on specific gravity, live load and traffic load calculated using "Loading for Bridges" (SNI 1725-2016), crane load using Liebherr Brand Ship to Shore Gantry Cranes specifications with a capacity of 50 tons, ship berthing load and mooring load ships are calculated based on Technical standards and comments for port and harbor facilities in Japan, OCDI, 2020, while earthquake loads are calculated using "Bridge planning against earthquake loads" (SNI 2833:2016). Steel piles are calculated using "specifications for structural steel buildings" (SNI 1729:2015) and reinforced concrete structures are calculated using "Structural concrete requirements for buildings and explanations" (SNI 2847 2019). Structural analysis for structures is carried out using the help of SAP2000 software. The results showed an increase in the ratio of iron by 38.57% and a decrease in the shear capacity of the punch by 56.57% at a span of 5.2 meters. Meanwhile, for a span of 10.4 meters, an increase in iron ratio of 38.57% was obtained and a decrease in the shear capacity of the puncher was 56.57%. these results were obtained by modifying conventional precast floor slabs with hollow core slab precast floor plates
