Based on reliability theory , the current seismic design code gbj11 - 89 and the previous research results of the same occupation , the seismic reliability analysis and the seismic design for the reinforced concrete frames are studied in this thesis . the major contents are summarized as follows : ( 1 ) seismic reliability of reinforced concrete beams designed following the current seismic design code is analyzed 本文以可靠度理論為基礎(chǔ),結(jié)合現(xiàn)行建筑抗震設(shè)計規(guī)范( gbj11 - 89 ) ,在廣泛借鑒國、內(nèi)外同行研究成果的基礎(chǔ)上,針對鋼筋混凝土框架結(jié)構(gòu)構(gòu)件和體系抗震可靠度分析與設(shè)計的一系列問題進行了研究,主要研究內(nèi)容為: ( 1 )針對按現(xiàn)行建筑抗震設(shè)計規(guī)范設(shè)計的鋼筋混凝土梁進行抗彎、抗剪可靠度分析。
According to the code for aseismatic design of building structure ( gbj11 - 89 ) , the seismic base - shear method has always been used to calculate the seismic response of building structures . in those structures , their weights and rigidities equally distribute along their heights which do not exceed 40m , and their deformations are mostly the shearing type ( when the structures " ratio of height and width are smaller than 4 ) 我國《建筑抗震設(shè)計規(guī)范》 ( gbj11 ? 89 )中規(guī)定,對于重量和剛度沿高度分布比較均勻、高度不超過40m ,并以剪切變形為主(房屋高寬比小于4時)的結(jié)構(gòu),可采用近似計算法,即底部剪力法來計算其地震響應。
