<br />63 <br /> <br />-~ <br /> <br />- <br /> <br />3.2 Anchorage <br /> <br />An intregal part of the design in any structure is the ttrength of the connections. Each part of a <br />building may have adequate strength, but if they iare not anchored together properly, an <br />unnecessary failure can still occur, It is important in ~ building that the superstructure is firmly <br />anchored to the foundation wall. Otherwise the buildin!; could slide off the foundation due to large <br />hydrodynamic loads, or it could lift off the foundatidn due to large buoyant loads, <br /> <br />1/2" ANCHOR <br />BOLT-4' O.C. <br /> <br /> <br />STudls <br /> <br />EXTERIOR <br />SHEATHING <br /> <br />SOL$PLATE <br />, SUB- FLOOR <br /> <br />BAND <br />(HEADER) <br /> <br />---~..--..-I ~__ <br />i JOISTS <br />-~+.~~ <br />--L-C: <br /> <br />PLATE <br /> <br />.-:,- FOUNDATION <br />WALL <br /> <br />'::~ <br /> <br />.:-: <br /> <br />Figure 7,9, Typical sill .,ssert,bly, (Reference 30) <br /> <br />The typical house will have the sill assembly shown in Figure 7.9.
