Abstract
The population density and sea flooding cause the reduction in residential land and land area each year. The way to cope with this condition is by creating a floating house. In constructing a building above water, the shape and strength of the beam must be taken into account by considering strong materials and structure constructions such as ferrocement. This study analyzes the structural and connection strength between pontoon ferrocements sized 120×120×100 with 3 cm thickness and varied connection among the pontoons. The connection variations include the connection of steel plate with a thickness of 3 cm and the connection of round bars with a thickness of 4 cm. The modeling is constructed in the software using finite element method and linear static analysis. The analysis of the two types of connections after given the pressure of seawater and house load shows the stress value of steel plate connection is 107 MPa and the stress value of round bars connection is 50 MPa. The result shows that both connections are considered safe given the fact that based on the Rules of Indonesian Classification Bureau, the allowed stress for steel plate is 235 MPa and for bars is 255 MPa. It means that the structures are safe. The trim pontoon condition resulted from the model creation using Maxsurf and Hydromax Software is trim stern with the height of laden stern is 0.669 m and the height of laden bow is 0.358 m.
