[提要]  提出了在框架頂部設(shè)置集中耗能層概念，并給出了雙線性強(qiáng)化連接模型。利用線性平穩(wěn)隨機(jī)響應(yīng)和非線性逐步積分法分析了設(shè)有集中耗能層的框架各梁柱的應(yīng)變能分布情況，結(jié)果表明能量的吸收和耗散效果十分明顯。
[關(guān)鍵詞]  框架結(jié)構(gòu) 地震能量 轉(zhuǎn)移 耗散

The layer for gathering and dissipating seismic energy connected on the top of frame structure is presented, and also its connecting moduls with bilinear strengthening property is given. Utilizing the linear stochastic process and calculation of step by step integration, strain energy distributed in beams and columns of frame setting on the layer is analysed, the results show that energy transferring and dissipating are very clearly.
Keywords: frame structure; transferring; dissipating;  seismic energy
