Compared two kinds of scale code , the frame superimposed scale code is better . from the further studies , an encoding method of frame superimposed is found out . some examples of this encoding method result are listed 通過對幀重疊編碼方法的編碼排列過程的研究,提出了幀重疊編碼方法的反碼優(yōu)先編碼排列過程,并給出了編碼排列過程實(shí)例。
In the end , the thesis put forward a prototype of computer - aided conceptual design system of mechanism and discussed in detail the process and methods of frame reasoning and solution finding of the system under the control of the conceptual design process 論文最后提出了一個(gè)計(jì)算機(jī)輔助機(jī)構(gòu)概念設(shè)計(jì)系統(tǒng)的原型,并且詳細(xì)闡述了系統(tǒng)在概念設(shè)計(jì)過程控制下進(jìn)行的框架推理求解過程和方法。
Instruction about first order analysis method of frames is given by most of the current textbooks on mechanics of structure , and this method is generally used by civil engineers in calculating the internal forces of the frames , however , as the first order analysis does not consider of the additional internal forces caused by the global lateral displacement of the frame , the solution given by this way is obviously not very accurate and safe 目前的結(jié)構(gòu)力學(xué)教材一般只講授框架的一階內(nèi)力分析方法,建筑結(jié)構(gòu)設(shè)計(jì)人員也普遍采用一階的分析方法對框架進(jìn)行內(nèi)力分析。而框架的一階內(nèi)力分析未考慮因整個(gè)框架側(cè)移引起的內(nèi)力附加值,這個(gè)結(jié)果顯然是不夠精確且偏于不安全的。
It is hoped that , through the continually and thoroughly research on the disciplinarians of the failure dependence of the rc structures under various kinds earthquake actions , the simplified calculation method of frame construction system reliability could be obtained , and the system reliability analysis theory could be applied to design criterions as soon as possible 我們希望,通過對本課題的持續(xù)性和深入性的研究,找出各種地震作用下,框架結(jié)構(gòu)的失效相關(guān)性規(guī)律,進(jìn)而給出各種地震作用下框架結(jié)構(gòu)體系可靠度的簡化計(jì)算方法,為結(jié)構(gòu)體系可靠度理論早日進(jìn)入建筑結(jié)構(gòu)規(guī)范提供必要的理論支持。
To date , structure engineers still adopt designing method of frame - shear wall structure rather than considering common action of pier wall and transition beam and the problem of stress - distribution complication arises from here . this paper provides the research object which is a 13 - stories frame supported short pier shear wall structure with different pier strength coefficients and integrity coefficients , focus on stress distribution of two - short - pier shear wall and three - short - pier wall under vertical loads and horizontal loads . it also concludes variational rules of internal force of transition floors in this structure 本文以具有不同整體性系數(shù)和肢強(qiáng)系數(shù)的13層框支短肢剪力墻結(jié)構(gòu)為研究對象,運(yùn)用ansys8 . 1有限元分析軟件,研究了雙肢墻、三肢墻和轉(zhuǎn)換梁等結(jié)構(gòu)構(gòu)件在豎向荷載與水平荷載作用下的應(yīng)力分布特點(diǎn),總結(jié)了帶梁式轉(zhuǎn)換層的短肢剪力墻結(jié)構(gòu)中轉(zhuǎn)換梁的內(nèi)力隨著墻肢截面高度的變化規(guī)律,為框支短肢剪力墻結(jié)構(gòu)的分析和設(shè)計(jì)提供了理論基礎(chǔ)。
The second research method is positivist study . this paper selects the olympic reports of six summer olympics from 1984 to 2004 in the china sport newspaper as the objects of text analysis . by the method of framing analysis , and adopting some data properly by quantitative analysis , it analyzes the representation and construction of national identities in the olympic reports from the micro - level 本文的研究方法之二為實(shí)證研究,以1984年洛杉磯奧運(yùn)會(huì)至2004年雅典奧運(yùn)會(huì)期間《中國體育報(bào)》六屆夏季奧運(yùn)會(huì)的奧運(yùn)報(bào)道作為本研究的文本分析對象,采用定性研究? ?框架分析的方法,并適當(dāng)采用一些定量分析的數(shù)據(jù),從微觀層面分析該報(bào)的奧運(yùn)報(bào)道中國家認(rèn)同的再現(xiàn)和建構(gòu)。
