摘   要

本工程為丹東職業(yè)中專辦公樓，為多層現(xiàn)澆鋼筋混凝土框架結(jié)構(gòu)。結(jié)構(gòu)共五層，底層層高3.9m，其它層層高均為3.6m，建筑物總高度為19.3m，室內(nèi)外高差0.6m，建筑面積為6298.37m2。本次設(shè)計主要包括建筑設(shè)計和結(jié)構(gòu)設(shè)計兩大部分。

建筑設(shè)計部分依據(jù)《辦公建筑設(shè)計規(guī)范 JGJ67-89》、《工程建設(shè)標(biāo)準(zhǔn)強(qiáng)制性條文 房屋建筑部分》、《房屋建筑制圖統(tǒng)一標(biāo)準(zhǔn) GB-T50001-2001》和任務(wù)書進(jìn)行設(shè)計，首先根據(jù)建設(shè)用地條件和建筑使用功能、周邊環(huán)境特點，進(jìn)行平面定位設(shè)計，并根據(jù)“適用、安全、經(jīng)濟(jì)、美觀”的原則，進(jìn)行平面設(shè)計、立面設(shè)計及剖面設(shè)計。

結(jié)構(gòu)設(shè)計部分依據(jù)《建筑荷載規(guī)范 GB50009-2001 》、《建筑抗震設(shè)計規(guī)范GB50011- 2001》、《混凝土結(jié)構(gòu)設(shè)計規(guī)范 GB5010- 2001》進(jìn)行設(shè)計,設(shè)計內(nèi)容主要包括結(jié)構(gòu)選型，梁、柱、墻等構(gòu)件尺寸的確定，一榀框架的荷載計算，采用底部剪力法計算框架所受水平荷載，用D值法計算水平地震作用下框架的內(nèi)力；豎向荷載主要包括恒荷載和活荷載，豎向荷載作用下框架內(nèi)力計算均采用彎矩二次分配法；求得的內(nèi)力后進(jìn)行內(nèi)力組合，并考慮三級抗震等級下強(qiáng)柱弱梁和強(qiáng)剪弱彎的計算，最后求得截面配筋，然后根據(jù)地質(zhì)情況進(jìn)行獨立基礎(chǔ)和聯(lián)合基礎(chǔ)的設(shè)計；此外還有屋蓋、樓蓋、樓梯、雨篷等構(gòu)件的設(shè)計。

最后完成建筑圖、結(jié)構(gòu)布置圖、梁柱配筋圖及詳圖，以上均采用CAD軟件進(jìn)行計算機(jī)繪圖。

The Design Of Office Building Of Dandong Vocational School

  

Abstract

This is an office building. It is a multi–layer reinforced concrete frame. It has five floors, the height of the first floor is 3.9 meters, and the height of other floors is 3.6 meters, The height of the whole building is 19.3 meters .The building area is 6298.37 m2. This design has two parts, architecture design and structure design.

The architecture design part was devised based on <architectural design specifi- cation JGJ 67-89> , < The Compulsory Provisions of Engineering Construction standards Building>, < Unified standard for buildingdrawin> and the project description carry, and according to the principle of “suitable, safe, economical, artistic”, to carry on the plane design, the vertical surface design and the section plane design.

The structure design part was devised based on < building code GB50009-2001> , <regulating the anti-seismic design specification GB50011-2001>, <conc- rete structure design codes GB5010-2001>. This design concludes the choice of structure, the investigation of size of beams,columns and wall comporent, a frame’s load computation, one section, reinforcement, main frame under horizontal and vertical load, the horizontal load is main considerated by the earthquake, bottom shear method to calculate the horizontal load, caleulate with D value calculation method under horizontal earthquake the internal frame.Vertical load calcu- lateion framework by bending moment distribution of law; then according to section of the reinforcement of geological conditions for independent foundation and joint foundation design, Besides,it also has the design of roof, fioor stair, the component and so on. 

Finally finish building, structure layout and reinforcement of detail drawing and beams. All the design carrys on the computer graphics with software of CAD.

Keywords：frame structure, load calculation, internal force calculation, section reinforcement
