簡(jiǎn)介：近年來(lái)，隨著經(jīng)濟(jì)的進(jìn)一步發(fā)展和科學(xué)技術(shù)水平的不斷提高，高層建筑的建設(shè)速度在逐年增加而許多結(jié)構(gòu)在地震作用下的破壞也暴露出現(xiàn)行抗震設(shè)計(jì)理論的不足，人們需要建立新的結(jié)構(gòu)抗震性能評(píng)估理論和方法，因此提出了基于性能的抗震設(shè)計(jì)思想。我國(guó)高層建筑愈來(lái)愈高，建筑高度不斷增加，建筑功能和類(lèi)型愈來(lái)愈復(fù)雜，結(jié)構(gòu)體系更加多樣化，地區(qū)分布更加廣泛。結(jié)構(gòu)抗震概念設(shè)計(jì)對(duì)結(jié)構(gòu)的抗震性能起決定性作用，而高層建筑結(jié)構(gòu)的選型與結(jié)構(gòu)布置在結(jié)構(gòu)抗震概念設(shè)計(jì)中占有極其重要的地位，它們直接影響著結(jié)構(gòu)的安全性與經(jīng)濟(jì)性?？蚣芗袅Y(jié)構(gòu)體系盡管已大量應(yīng)用于工程實(shí)踐，但理論研究方面尚處在探索、完善階段，本文以一幢12層的框剪結(jié)構(gòu)作為研究對(duì)象例，利用ASGEN對(duì)框架剪力墻結(jié)構(gòu)進(jìn)行了有限元分析，從強(qiáng)度和變形兩方面來(lái)檢驗(yàn)框架剪力墻結(jié)構(gòu)的安全和抗震可靠度。本文詳細(xì)闡述了有限元理論的基本思想，通過(guò)對(duì)結(jié)構(gòu)的正確規(guī)劃，建立符合實(shí)際的有限元模型，以使有限元模型能準(zhǔn)確模擬靜力分析和動(dòng)力分析。根據(jù)該結(jié)構(gòu)各構(gòu)件的受力特征，將整個(gè)結(jié)構(gòu)模擬為空間梁、板單元的三維整體計(jì)算模型，并對(duì)有限元分析模型進(jìn)行靜力、反應(yīng)譜法及時(shí)程分析的動(dòng)力計(jì)算。通過(guò)對(duì)結(jié)構(gòu)進(jìn)行模態(tài)分析，得出結(jié)構(gòu)的振動(dòng)特性，然后通過(guò)振型分解法，驗(yàn)算了在地震作用下墻體的剪力設(shè)計(jì)值以及各樓層的位移值，并通過(guò)計(jì)算公式對(duì)結(jié)構(gòu)在地震作用下的承載力的驗(yàn)算與對(duì)比，得出了結(jié)構(gòu)的抗剪承載能力和儲(chǔ)備。通過(guò)時(shí)程分析，驗(yàn)算了結(jié)構(gòu)各層的層間剪力和位移的時(shí)程變化，以及各層層間剪力和位移在整個(gè)地震波的時(shí)間歷程中的最大值。以上結(jié)論對(duì)框架剪力墻結(jié)構(gòu)體系的設(shè)計(jì)具有較好的參考價(jià)值。

簡(jiǎn)介：汶川地震造成直接經(jīng)濟(jì)損失創(chuàng)新中國(guó)成立以來(lái)之最，大部分經(jīng)濟(jì)損失是發(fā)生在震源附近場(chǎng)地，這些啟發(fā)我要對(duì)近場(chǎng)地震做更多的研究。近場(chǎng)地震特性復(fù)雜，本文僅研究有速度脈沖近場(chǎng)地震。第一條速度脈沖地震記錄被發(fā)現(xiàn)到現(xiàn)在已有三十多年了，目前雖然在有速度脈沖近場(chǎng)地震動(dòng)研究方面取得了一定的進(jìn)展，也得到了一些有用的結(jié)論，但速度脈沖對(duì)結(jié)構(gòu)的破壞程度、罕遇地震條件下，靜力彈塑性分析方法是否能代替速度脈沖動(dòng)力時(shí)程分析方法等問(wèn)題，目前研究較少；且中國(guó)抗震設(shè)計(jì)規(guī)范也沒(méi)有考慮速度脈沖的影響。針對(duì)以上問(wèn)題，本文進(jìn)行了以下方面的工作1分析了大量近場(chǎng)地震記錄，選擇了部分有明顯速度脈沖地震記錄，比較各種地震記錄加速度反應(yīng)譜，研究各國(guó)規(guī)范近場(chǎng)反應(yīng)譜，指出修改中國(guó)建筑設(shè)計(jì)規(guī)范加入近場(chǎng)反應(yīng)譜的必要性。2研究一棟7層框架結(jié)構(gòu)在速度脈沖近場(chǎng)地震作用下的動(dòng)力響應(yīng)。比較了速度脈沖近場(chǎng)、無(wú)速度脈沖近場(chǎng)和遠(yuǎn)場(chǎng)地震在多遇和罕遇地震條件下結(jié)構(gòu)動(dòng)力響應(yīng)；研究了靜力彈塑性分析基本原理和實(shí)現(xiàn)過(guò)程，根據(jù)中美規(guī)范反應(yīng)譜，推導(dǎo)了其使用參數(shù)的表達(dá)式，比較了靜力彈塑性分析和動(dòng)力彈塑性分析對(duì)結(jié)構(gòu)的計(jì)算結(jié)果。3研究一棟12層框剪結(jié)構(gòu)在速度脈沖近場(chǎng)地震作用下的動(dòng)力響應(yīng)。比較了速度脈沖近場(chǎng)、無(wú)速度脈沖近場(chǎng)和遠(yuǎn)場(chǎng)地震在多遇和罕遇地震條件下結(jié)構(gòu)動(dòng)力響應(yīng)；比較了靜力彈塑性分析和動(dòng)力彈塑性分析對(duì)結(jié)構(gòu)的計(jì)算結(jié)果。
