Translated Title
Study on the Integral Stability and P-Δeffect of One Fabricated Steel Frame Structure with inclined supports
Translated Abstract
Fabricated steel structure is the only way for industrialization of steel structure, due to its advantages of fast construction speed, factory production, and environmental protection.Although some building examples are existing at home and abroad, they are mostly low-rise structures and seldom adopted in high-rise field.This paper introduces the structure design and connections test of the high-rise fabricated steel frame with connections enhanced by diagonal bracings, which has been applied in the T30 apartment project of Broad Group.Through the finite element numerical simulation of whole structure, the structural natural period of vibration, the modal and the lateral stiffness characteristics are obtained by the modal analysis, the P-Δeffect analysis and the overall stability analysis separately.In this research, the influence rule of P-Δ effect has been acquired, the ultimate load of the structure and the security reserve characteristics has been obtained, the failure mode and mechanism of the system has been achieved.The design method summarized in this paper have important reference value for future research and design work of similar fabricated steel structure.
