Application of Structural Principles in Construction 2INTRODUCTIONThis report is about the assessment of a steel portal framed construction having a widespan which is already under construction or already completed. Some of the information of the building in question that will be considered in this assessment include footing system, structural system, floor system, wall system, services, and roof system. The building which will be used in the assessment is an already complete Old Parliament House Building which was designed by the John Smith who was the Chief Commonwealth architect. The construction in based in the Perth GPO, Australia. The Old Parliament House construction is a medium rise construction which is made up of three storey building composing to chambers majorly Senate and House of Representatives. The sections of the Parliament House which are assessed in this report include its footing system, structural system, floor system, wall system, services, and roof system[ CITATION Jam12 \l 2057 ]. Footing SystemThe footing system includes the structures that transfer the weight of the facility to thematerial of foundation which is mostly soil. The systems of footing should be designed to suitthe variations of soil conditions and also offer enough tie-down for the Old Parliament House

A good footing system attains these requirements while reducing the quantities of materials and site disturbance with huge embodies energy such as steel and concrete. For the adequate performance of the Old Parliament House, a firmfoundation which includes installed footings of sufficient size which is involved in supportingthe structure and preventing excessive settlement[ CITATION CAr14 \l 2057 ]. The foundations can be categorized as deep foundations or shallow foundations depending on the load-transfer member depth below the facility as well as the transfer load mechanism type. The system of foundation depends on the on the compressibility and strength of the soils around the facility, loading conditions proposed, and the performance criteria of the project. The designs of the foundation are based on the soil's assumed bearing capacity at the site of the facility. The shallow type of foundation gives the most economical system of foundation and is used typically for commercial and residential buildings. The typeof soil in which this construction was built on was clay soil[ CITATION CAr14 \l 2057 ]. During the construction of the Old Parliament House, the soil where the site was to beconstructed has poor clay soil condition hence there was a need to use deep foundations for the provision of bearing capacity and limit settlement. The footing systems are normally covered in the code of the building and sized depending on the weight of the building and the soil’s bearing capacity. The types of footing system that were used in the construction of the foundation of the Old Parliament Building include grade beam footing, continuous spread footing and spot footings. These types of footings were used in the foundation as shown in figure 2 below:

The beam footings below was used in the sections of the site that had extremely relative ground[ CITATION CAr14 \l 2057 ]. The type of foundation that was used in the construction of the facility was the stem wall foundation which is also known as the continuous foundation walls. This type of foundation is constructed frequently of poured concrete or reinforced masonry, supported by footing that is continuously reinforced concrete as shown in figure 3 below. Structural SystemThe structural system of the Old Parliament building entails the frame supports of the building’s loads as well as how the building resist wind loads. The type of frames implemented in the construction of the building between the structural members such as column and rafter was portal frames. The portal frames are normally comprised of the horizontal and columns or even after that are pitched and joined through resisting connectionsof the moment. The resistance to the vertical and lateral actions is offered by the connection’s
