（廈門市抗震辦 361004）[提要] 在簡化假設(shè)的基礎(chǔ)上，推導(dǎo)出了規(guī)則框架結(jié)構(gòu)自振周期、振型、地震作用、樓層剪力及水平位移等的鰓析表達式，并制成表格。利用本文結(jié)果，可方便地進行規(guī)則框架的抗震設(shè)計和抗震設(shè)防審查。算例表明，應(yīng)用于一般非規(guī)則框架的抗震分析時，其精度也是令人滿意的。
[關(guān)鍵詞] 框架結(jié)構(gòu) 解析表達式 抗震分析 抗震設(shè)防審查Analytical formulas for natural periods, vibration modes, earthquake actions, floor shear forces and horizontal displacements of regular frame structures are derived out and tabulated, which can be uesd conveniently for seismic design of frame structrures and for examination of the results of these designs. Finally, several examples of irregular frames are given to test the effectiveness and precision of the method.
Keywords: frame structure; seismic design; analytical solution; simplified method
