Application of Structural Principles in Construction2INTRODUCTIONThis 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 ofthe 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 whichwill be used in the assessment is an already complete Old Parliament House Building whichwas designed by the John Smith who was the Chief Commonwealth architect. Theconstruction in based in the Perth GPO, Australia.The Old Parliament House construction is a medium rise construction which is madeup of three storey building composing to chambers majorly Senate and House ofRepresentatives. The sections of the Parliament House which are assessed in this reportinclude its footing system, structural system, floor system, wall system, services, and roofsystem[ 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 requirementswhile reducing the quantities of materials and site disturbance with huge embodies energysuch 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 foundationsdepending on the load-transfer member depth below the facility as well as the transfer loadmechanism type. The system of foundation depends on the on the compressibility andstrength of the soils around the facility, loading conditions proposed, and the performancecriteria of the project. The designs of the foundation are based on the soil's assumed bearingcapacity at the site of the facility. The shallow type of foundation gives the most economicalsystem 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 forthe provision of bearing capacity and limit settlement. The footing systems are normallycovered in the code of the building and sized depending on the weight of the building and thesoil’s bearing capacity. The types of footing system that were used in the construction of thefoundation of the Old Parliament Building include grade beam footing, continuous spreadfooting and spot footings. These types of footings were used in the foundation as shown infigure 2 below:

The beam footings below was used in the sections of the site that hadextremely relative ground[ CITATION CAr14 \l 2057 ].The type of foundation that was used in the construction of the facility was the stemwall foundation which is also known as the continuous foundation walls. This type offoundation is constructed frequently of poured concrete or reinforced masonry, supported byfooting 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 thebuilding’s loads as well as how the building resist wind loads. The type of framesimplemented in the construction of the building between the structural members such ascolumn and rafter was portal frames. The portal frames are normally comprised of thehorizontal 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
