The Aseismic Conceptual Design Of The Gymnasium Based On Optimal Fortification Intensity

In the earlier stage of civil engineering's design, there are many serious problemswhich (in need of) need scientific adhocery including construction object's feasibilityargument ,construction object 'total planning and function optimization,structuralform selection and the decision of structural fortification intensity. All these decisionsbelong to conceptual design ,which have more effection on civil engineering thanoptimal design mainly based on (in which) structural calculation (is cardinal )presently. Gymnasium belongs to big utility structure that's investment and loss are allhuge, so it is important to know its optimal fortification intensity. This paper solvesseismic conceptual design mainly based on mathematical model of optimalfortification intensity in allusion to gymnasium as considering both the structure'costand its economic and social benefit. The gymnasium's upper part is selectedintellectually in consideration of all kinds of factor, and its main part is chiefly madeup of skeleton structure which form is symmetrization and stress is even. In actualprojects controlling, the axial compression ratio of the frame columes can reflect thestructural aseismic performance. So it can ascertain beam and colume's cubic thatcalculates the structural cost. Calculating structural loss expectation consider thegymnasium's first investment ,equipment investment ,galleryful and businesscircumstance. At last making goal function(the sum of cost and loss expectation) driveto minimum decide the structural optimal fortification intensity. In this paper according to an actural project modeling gymnasium building thatcontrols the axial compression ratio at 0.4 and 0.5 solves.Its optimal fortificationintensity .It can be seen from data analysis that controlling frame colume's axialcompression ratio can expedientlysolve its optimal fortification intensity and thenumder of axial compression ratio have no influence on it .It is important to aseismicstructure that the optimal fortification intensity calculated considerssynthetically thegymnasium's cost ,loss expectation and its multistage failure criterion . â…¡ABSTRACT The theoretical model of optimal fortification intensity can apply to the earlierstage of gymnasium's aseismic conceptual design and can apply to the actual designas theoretical basis.
