With heaps of time, the sevenday Chinese 請您刪除一下內(nèi)容， O(∩_∩)O謝謝?。?！ National Day holiday could be the best occasion to enjoy a destination. However, it can also be the easiest way to ruin how you feel about a place and you may bee more fatigued after the holiday, due to battling the large crowds. During peak season, a dream about a place can turn to nightmare without careful planning, especially if you travel with children and older people. As most Chinese people will take the holiday to visit domestic tourist destinations, crowds and busy traffic are inevitable at most places. Also to be expected are increasing transport and acmodation prices, with the possibility that there will be no rooms available. It is also mon that you39。 答 ：梁斜截面的三種破壞形態(tài)及其破壞條件： 1)剪跨比較小時(shí)或剪跨比適中但配箍率過大時(shí)，發(fā)生斜壓破壞； 2）剪跨比較大或配箍率較小時(shí)，發(fā)生斜拉破壞； 3）剪跨比適中，配箍率合適時(shí)，發(fā)生剪壓破壞。 A.≤ 8 B.≤ C.≤ 5 D≤ 6 鋼筋混凝土受壓柱，大小偏壓構(gòu)件的判斷條件是（ C）。 （ ） ，采用水泥砂漿與混合砂漿砌筑的砌體強(qiáng)度相 等。 （√） ，不需考慮結(jié)構(gòu)重要性系數(shù)。 二、選擇題 （ A）強(qiáng)度作為混凝土各種力學(xué)指標(biāo)的代表值。 ，發(fā)生斜壓、剪壓、斜拉破壞形態(tài)時(shí)，梁的斜截面抗剪承載力的大致關(guān)系是（ A）。m的作用，已在受拉區(qū)配置有 4 根直徑 25mm 的鋼筋（ As=1964mm2），試驗(yàn)算截面安全與否。 Festival. In this day, g irls will throw a sewing needle into a bowl full of water on the night of Qixi as a test of embroidery skills. If the needle floats on top of the water instead of sinking, it proves the girl is a skilled embroiders. Single women also pray for finding a good husband in the future. And the newly married women pray to bee pregnant quickly. Tradition transformed The love story of Niulang and Zhinu, and the Qixi Festival have been handed down for generations. Yet these ancient traditions and customs are slowly dying out. Many modern Chinese, particularly youngsters, seem to know more about St Valentine39。面積所配置的縱向受力鋼筋 ,1964,/360,/ 22/2 mmmmNfmmNf yc ?? b/0? 8 10 12 ? 提示： )(, ////sycUS AfAfNAA ??? ??。 2）第二階段一帶裂縫工作階段，此階段截面的應(yīng)力狀態(tài)可以作為裂縫寬度和變形驗(yàn)算的依據(jù)。 混凝土構(gòu)件，若其縱筋配筋率小于最小配筋率，我們一般稱之為（ B）。 （ ） ，斜拉破壞和斜壓破壞是脆性破壞。 （√） 。 20mm B. 不小于鋼筋直徑和 25mm C. 不小于鋼筋直徑和 30mm D. 不小于鋼筋直徑和 40mm ，布置有單排縱向受力鋼筋的梁，其截面有效高度一般可取（ B）。 ？每一個(gè)階段末的應(yīng)力狀態(tài)可以作為什么驗(yàn)算的依據(jù)？ 答： 1）第一階段一彈性階段，此階段截面的應(yīng)力狀態(tài)是抗裂驗(yàn)算的依據(jù) 。 已知： 穩(wěn)定系數(shù)見下表。s Day on February 14, characterized by bouquets of roses, chocolates and romantic candlelight dinners, than they do about their homegrown day for lovers.
