【正文】 內(nèi)蒙古科技大學(xué)本科生畢業(yè)設(shè)計 I 內(nèi)蒙古科技大學(xué)第二綜合實驗樓（方案二） 摘 要 本設(shè)計是 內(nèi)蒙古科技大學(xué)第二綜合實驗樓（方案二） ，該工程為五層框架結(jié)構(gòu)，建筑總高度為 ，建筑總面積約 18000 ㎡，抗震設(shè)防烈度 8度，場地類別為 II類，設(shè)計中不考慮風(fēng)壓，雪壓為 kN/㎡，本設(shè)計主要對結(jié)構(gòu)方案中 Q 軸一榀框架進(jìn)行了結(jié)構(gòu)抗震設(shè)計。 本設(shè)計在確定結(jié)構(gòu)布置方案之后，先進(jìn)行了重力荷載代表值的計算；接著利用能量法求出自振周期，用底部剪力法計算了水平地震作用下的側(cè)移大小；進(jìn)而利用 D 值法求解了水平荷載作用 下框架的內(nèi)力；隨后用彎矩二次分配法計算了豎向荷載作用下的框架內(nèi)力，然后進(jìn)行了內(nèi)力組合，并找出最不利的一組或幾組內(nèi)力，進(jìn)行梁、柱截面和樓梯配筋計算。樓板設(shè)計包括樓段板配筋、休息平臺梁配筋。最后是基礎(chǔ)設(shè)計，需要確定基礎(chǔ)底面尺寸，進(jìn)行抗沖切驗算，并計算配筋，在手工計算完成后，還應(yīng)用 PKPM 軟件對整個結(jié)構(gòu)進(jìn)行電算，并繪制結(jié)構(gòu)施工圖。 關(guān)鍵詞 ：框架結(jié)構(gòu)；抗震設(shè)計；內(nèi)力組合；截面設(shè)計；電算 內(nèi)蒙古科技大學(xué)本科生畢業(yè)設(shè)計 II Inner Mongolia University Science ＆ Technology the second of the teaching and experiment prehensive building(scheme II) Abstract This design is Inner Mongolia University Science ＆ Teaching and experiment prehensive building( Scheme II),the building is five stores, the structure of which is framework. The total area of building is 18000m ㎡ ,The total height is , and the seismic fortification intensity is 8 and its location category is this design, the wind pressure is not considered, the snow pressure is respectively kN/㎡ .This design choice the axis of Q to calculate the internal force bination. After confirming the structural arrangement, first of all, the representative value of gravity load is calculated. After that, the structure under the horizontal earthquake action is confirmed by baseshear method,and then solve the internal force of frame under the horizontal load by the method of Dvalue. Subsequently, the internal force of frame under the vertical load by the method of second moment disadvantage modular design value to carry out the calculation of beams , columns and floors reinforced section .The design of staircases includes those of the reinforcement of staircase,the reinforcement of the rest platform and the reinforcement of beam platform. What es last is the basic design , which needs to identify basic bottom size, check punching and calculate reinforcement. In the end, the main structure is calculated using the software of PKPM after finishing the manual calculation, and draw up the construction drawings. The key words: frame； seismic design； internal force bination； section design； electric calculation. 內(nèi)蒙古科技大學(xué)本科生畢業(yè)設(shè)計 III 目 錄 摘要 ...........................................................................................................................................
