［摘要］隨著經濟、科技的發(fā)展，人們對建筑物抗震的要求越來越高，傳統(tǒng)的建筑施工方法，往往在樓板中配以鋼筋，本文在學習了大量的文獻之后，引入了一種新的建筑材料——玻璃纖維筋。并且以兩層單跨預制板框架結構作為研究對象，建立其參數(shù)化模型,用有限元分析軟件ABAQUS對該整體結構進行反應譜分析，得到其自振頻率并確定其在地震作用下的響應。通過對比分析這兩種結構的前3階自振頻率、兩種不同結構的反應譜樓層最大位移以及在反應譜分析中不同構件所承受的最大內力，得出這種新的建筑材料在地震作用下能夠更好地發(fā)揮本身的優(yōu)越性，能夠很好地抵抗地震作用，從而維護建筑本身。最后給出了玻璃纖維筋在板結構中可以取代鋼筋建議，希望對建筑結構以后的發(fā)展有所啟示，對建筑抗震研究有所幫助。

Abstract: With the development of economy and technology, the demand of seismic becomes more, with reinforcement in the floor is a traditional building construction method. After learning a lot of reference books. A two layer of a span precast slab frame structure was selected as the research object and a parametric model of grid frame was established in order to research response spectrum analysis of the whole structure with finite element analysis software ABAQUS. The static structure vibration frequency of itself was got to determine the structure response under earthquake action. Through comparative analysis of the first three natural frequencies maximum displacement of floor response spectra, the maximum internal force of different structural member in the response spectrum analysis of these two structures, obtain this new building material can better play their own advantages, can better withstand seismic action, so as to maintain the building itself. Finally, the glass fiber reinforcement in the slab structure can replace steel was suggested. Meanwhile hoping that it can have implications for the future development of the seismic research and building structure.
Keywords: ABAQUS; response spectrum analysis; self vibration frequency; glass fiber bar; seismic action
