Need help with my writing homework on Preliminary Design and Analysis of an Exhibition Centre in Hyde Park. Write a 1250 word paper answering; The framing of the building generally uses a combination of composite beams alongside open-web steel joists which are primarily supported using trusses. Additionally, it uses heavy long-span girders in various locations where trusses are not permitted. The deflections of the floor as well as vibration have as well been accorded significant concern and utilized a concrete slab of thickness 3-1/2 inches.
The braced steel frames offer a lateral load resistance for the dissipation of seismic energy. In order to arrange braces for the large format truss structure, the structure used truss load paths both for vertical and lateral loading. Nonetheless, there was little option for lateral brace usage. Through the strategic selection of locations for lateral resistance proportional to the mass of the building, the system is balanced in line with the building mass and hence minimizes torsional motion associated with the building.
The distribution of both dead and dynamic loading is considered. The dead load basically considers the weight of the roof. On the other hand, seismic and wind loading are considered in the analysis of the loading conditions to which the building is to be subjected. Seismic action effects are evaluated taking into account the presence of all gravity loads displayed in following action combination (Ajaya, 2010):
Just like is the case in calculations, earthquakes show a more extreme effect on the building as compared to wind. There is no visible deformation resulting from the wind effect. Rather these effects conform to quantitative analysis findings and remain negligible. See the table for details.
The results indicate that the building is self-sufficient. Sap2000 analysis confirms most of the results revealed by manual calculation. Based on all the results, it is evident that response spectrum analysis results compare well to the manual results obtained. Nonetheless, sap2000 analysis results show slightly higher values as compared to the manual. This is probably explained by varying CQC combination from the sap 2000 analysis. . .
