摘要本工程是沈阳东旭高中教学楼，为多层钢筋混凝土框架结构，共五层，底层层高3.6米，其他层层高也为3.6米，建筑物总高度为18.9米。在遵循“适用、安全、经济、美观”的设计原则和国家有关现行建筑结构设计规范与标准的基础上，进行了教学楼的建筑与结构初步设计，获得了该建筑物初步设计阶段的建筑CAD设计图纸与技术指标，确定了结构布置方案与结构计算模型。先进行了层间荷载代表值的计算，然后按底部剪力法计算水平地震荷载作用下大小，进而求出在水平荷载作用下的结构内力（弯矩、剪力、轴力）。接着计算竖向荷载（恒载、活荷载以及雪荷载）作用下的结构内力，找出最不利的一组或几组内力组合。选取最安全的结果计算配筋并绘图。此外还进行了结构方案中的室内楼梯的设计（完成了平台板，梯段板，平台梁等构件的内力和配筋计算）、楼盖的设计（完成了板的配筋和次梁的配筋）、基础的设计（完成了基础的配筋）关键词：钢筋混凝土，框架，结构设计AbstractThisisateachingbuildingofaDongxuchoolinshenyang.Itisamulti-layerreinforcedconcreteframe.Ithasfivestories,theheightofthefirststoreyis3.6meters,andtheheightofotherstoriesarea3.6metersto.Theheightofthewholebuildingis18.9meters.Inaccordancewiththedesignprincipleof“applicability、safety、economy、aesthetic”andthepresentcodesandstandardsofthearchitecturalandstructuraldesign,theprimaryarchitecturalandstructuraldesignofbuildingiscarriedout.AftergettingthearchitecturaldrawingfromCADdesign,theanthordecidesthestructuralschemeandthestructuralcalculationmodelWhenthedirectionsoftheframesisdetermined,firstlytheweightofeachflooriscalculated.Thenmakingtheamountofthehorizontalseismicforcecanbegotbywayofthebottom-shearforcemethod.Theseismicforcecanbeassignedaccordingtotheshearingstiffnessoftheframesofthedifferentaxis.Thentheinternalforce(bendingmoment,shearingforce，axialforce＆snowforce)inthestructureunderthehorizontalloadscanbeeasilycalculated.Afterthedeterminationoftheinternalforceunderthedeadandliveloads,thecombinationofinternalforcecanbemadebyusingtheExcelsoftware,whosepurposeistofindoneorseveralsetsofthemostadverseinternalforceofthewalllimbsandthecoterminousgirders,whichwillbethebasisofprotra...
