- Abstract
After the Indian Ocean Tsunami 2004 in Aceh, houses and other buildings were reconstructed by government and Non-Governmental Organizations (NGO). The new buildings near the coastline are open directly to similar tsunami attack. The layout of such new residential are normally arranged and aligned as rows of buildings. The front rows of the buildings suffer more tsunami force due to their location that are closer to the beach and the effect of the reflection from the adjacent buildings. This research aims to analyze the tsunami force on buildings of different types, and the effect of other buildings nearby. The research was conducted using a physical model at the Hydraulic and Hydrology Laboratory, Research Centre for Engineering Science, Universitas Gadjah Mada Indonesia. The physical model simulations were carried out in a flume of 24 m long, 1.45 m wide, and 1.5 m high, that was facilitated with tsunami generator based on dam break system. The models of the buildings were made of plywood and were placed in a row perpendicular to the flume. The distance between the buildings was varied to observe the effect of the gaps. The results show that the force on the building depends on the gap between the buildings. Although the effect of the gap was more significant on low buildings, the effect of force on high buildings was more sensitive to the change of the gap size. Simple equation for practical use is proposed to calculate the tsunami force on building with the effect of nearby buildings.
