Structural

The library has many parts to it construction that needs to be done in order for it to be ensured that the building will stay up over a long period of time with no underlying large scale decay.The structure of the library uses a steel frame support system. The reason for this support system  is because steel is more of a light weight material easily able to build the library skeletal structure. The steel is also very flexible which makes it possible for any of the bends and curves that the library may require in order to make the library`s options of shapes increase. The steel is more shallower as opposed to concrete in building the structure of the library. The less spaces needed for the steel is used to provide more space in the library for the building designers(Architectures) to work with and the visitors of the library to enjoy. The steel is also more durable a substance as opposed to using concrete. There will be cracking and weathering to worry about with concrete but with steel the corrosion is not much of a problem if the steel is treated. The building does involves light weight concrete and metal slabs. These are used more for the interior and the base. Braced frames are used for the seismic area. Braced frames are a structural system that is used primarily for the resistance of wind as well as seismic activity and forces. The system is made to work in tension in addition to compression. This system is made for the fact that the area that the library is located in is a high seismic area meaning frequent earthquakes. The steel in the structure of the library is more able to adapt to the motions and tremors that are caused by the earthquake as opposed to concrete. There are V shaped columns constructed within the library that are also made of steel. The foundation is sitting on a fill. Due to the nature of the soil in the area it was decided to use a better grade of soil which will in turn increase the stability or solidity of the building`s underlying foundation that is going to be built on top. The slab is on grade. The slab is a large slab of mostly concrete that is used as the base or foundation of the building in order to make the ground floor. The on grade means that it will be built on top of the fill. The design loads are from ASCE-7 code book.
