【正文】 合 肥 工 業(yè) 大 學(xué) 畢 業(yè) 設(shè) 計(jì) 年 月題 目： 多層綜合辦公樓 專 業(yè)： 土木工程 班 級(jí) : 學(xué) 號(hào)： 學(xué) 生姓名 ： I 摘 要 本工程采用框架結(jié)構(gòu)，主體五層局部六層，本地區(qū)抗震設(shè)防烈度為 7 度，場地類別為 II類。基本風(fēng)壓 ，基本雪壓 。樓蓋及屋蓋均采用現(xiàn)澆鋼筋混凝土結(jié)構(gòu)。 本設(shè)計(jì)主要進(jìn)行了結(jié)構(gòu)方案中第 10 軸橫向框架的結(jié)構(gòu)設(shè)計(jì)。在確定結(jié)構(gòu)布局之后，首先，按底部剪力法求出層間剪力 ，進(jìn)而求出在水平地震作用下的結(jié)構(gòu)內(nèi)力；其次，最后用彎矩分配法計(jì)算豎向荷載（恒載及活荷載）作用下的結(jié)構(gòu)內(nèi)力。并找出最不利的一組或幾組內(nèi)力組合，選取最安全的結(jié)果計(jì)算配筋并繪制施工圖。此外還進(jìn)行了方案中的連系梁，樓板和基礎(chǔ)的設(shè)計(jì)。 本設(shè)計(jì)嚴(yán)格遵循最新的國家規(guī)范標(biāo)準(zhǔn)，對(duì)設(shè)計(jì)的各個(gè)環(huán)節(jié)進(jìn)行綜合全面的考慮。適用、安全、經(jīng)濟(jì)、使用方便是本設(shè)計(jì)的基本原則。 關(guān)鍵詞： 框架結(jié)構(gòu) 荷載計(jì)算 內(nèi)力計(jì)算 計(jì)算配筋 II Abstract The project used the framework of the structure, the main fivestorey six local, regional seismic intensity of6 degrees maximum security, venue for the Class II category. The basic Pressure kN / m2, basic snow pressure kN / m2. Floor and roof are used castinplace reinforced concrete structure. The design for the main structure of the programme in the framework of Article 10 of the horizontal axis structural design. In determining the structure of the layout, first of all, according to law obtained at the bottom of the shear layer shear, thereby obtained under earthquake in the level of the structure of internal forces and secondly, D method used in the level of wind loads obtained under the structure of internal forces .The last moment with the distribution method vertical load (dead load and live load) under the structure of internal forces. And identify the most disadvantaged group or a bination of internal forces of several groups, select the most security and reinforcement Calculation of the results of the construction plans drawn. In addition, a programme of indoor staircase, floor and foundation design. The design strictly follow the latest national standards, the design of all aspects of a prehensive consideration. Application, security, economic, easy to use this design is the basic principle. Key words： frame structure load calculation internal force calculation calculation reinforcement III 目 錄 摘 要 ...........................................................................................................................................I ABSTRACT .............................................................................................................................
