20xx年中央電大統(tǒng)考本科《建筑結(jié)構(gòu)試驗》課程期末復(fù)習(xí)要點小抄參考-預(yù)覽頁
【正文】 觀測儀表工作是否正常；4）檢查現(xiàn)場組織工作和人員的工作情況，起演習(xí)作用。 9．鋼筋混凝土梁的裂縫觀測包括哪些內(nèi)容？ 答：鋼筋混凝土梁的裂縫觀測包括：及時地捕捉到第一條裂縫的出現(xiàn)，并盡可能準(zhǔn)確地記錄下此時的荷載值；按加載分級跟蹤描繪裂縫的開展情況，并測出裂縫的寬度。 11．簡述建筑結(jié)構(gòu)試驗中的真值、近似值和誤差三者的關(guān)系？ 答：真值是物理量本身所固有的，人們對物理量測量的目的就是尋求真值。 2．研究性疲勞試驗一般研究哪些內(nèi)容？ 答：研究性疲勞試驗一般研究以下內(nèi)容： 1）開裂荷載及開裂情況； 2）裂縫的寬度、長度、間距及其隨荷載重復(fù)次數(shù)的變化； 3）最大撓度及其變化； 4）疲勞極限； 5）疲勞破壞特征。 6．結(jié)構(gòu)抗震試驗的特點是什么？要求觀測的內(nèi)容有哪些？ 答：結(jié)構(gòu)抗震試驗的特點是荷載作用反復(fù)，結(jié)構(gòu)變形很大。 8．地震模擬振動臺動力加載試驗在抗震研究中的作用主要體現(xiàn)在哪些方面？ 答：地震模擬振動臺動力加載試驗的主要作用體現(xiàn)在： 1）研究結(jié)構(gòu)的動力特性、破壞機理及震害原因； 2）驗證抗震計算理論和計算模型的正確性； 3）研究動力相似理論，為模型試驗提供依據(jù)； 4）檢驗產(chǎn)品質(zhì)量，提高抗震性能，為生產(chǎn)服務(wù)； 5）為結(jié)構(gòu)抗震靜力試驗提供試驗依據(jù)。s top try scorer with nine, closely followed by TuivasaSheck with eight. But it is recently named Rugby League International Federation player of the year Sonny Bill Williams who has attracted the most interest in the tournament so far. The Kiwi with a tournament high 17 offloads has the chance of being the first player to win the World Cup in both rugby league and rugby union after triumphing with the All Blacks in 2020. I39。s Premier League match at Chelsea on Sunday. I am going to be at the match tomorrow and I have asked to meet Yaya Toure, he told BBC Sport. For me it39。s actions. CSKA said they were surprised and disappointed by Toure39。ve been great at all the unglamorous stuff that often goes unnoticed in the stands but not by your teammates. It is as though their entire tournament has been preparation for the final. In Johnathan Thurston, Cooper Cronk, Cameron Smith and either Billy Slater or Greg Inglis at full back they have a spine that is unmatched in rugby league. They have played in so many highpressure games a priceless asset going into Saturday. The Kiwis are a lot less experienced but winning a dramatic match like their semi final against England will do wonders for their confi dence. They defeated Australia in the Four Nations final in 2020 and the last World Cup, and know they can rise to the big occasion.
