摘要本工程为恒顺宾馆建设,采用框架结构,主体为五层,首层层 高为 4。2m,其余层高为 3。9m,总高为 20。8m。本地区抗震设防烈度为 7 度,场地类别为Ⅱ类场地,设计地震分组为第一组。主导风向为西 北风,基本风压 0。50 kN/m2,基本雪压 0。3 kN/m2。楼﹑屋盖均采用 现浇钢筋混凝土结构。85091
本设计主要进行了结构方案中横向框架第 6 轴抗震设计。在确 定框架布局之后,由于结构为 L 形,采用变形缝将结构分为相互独 立的两个部分,手算选取一部分来计算。先进行了重力荷载计算,然 后进行框架横向抗侧刚度的计算,进而按底部剪力法计算水平地震 荷载作用下大小,之后再进行在地震作用和风荷载作用下的内力(弯 矩、剪力、轴力)计算,接着计算竖向荷载(恒载及活荷载)作用 下的结构内力,随后进行内力组合并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。
整个结构在设计过程中,严格遵循相关的专业规范的要求,参 考相关资料和有关最新的国家标准规范,对设计的各个环节进行综 合全面的科学性考虑。总之,适用、安全、经济、使用方便是本设 计的原则。

Abstract The project for the construction of Hengshun Hotel, a framework structure, the main body of five layers, first storey 4。2m, the rest of the story is 3。9m, with a total height of 20。8m。 local seismic fortification intensity is 7 degrees, site classification for site class II, classification of design earthquake for the first group。 Dominant wind direction to the northwest wind, basic wind pressure 0。50 kn / m2, basic snow pressure
0。3 kN/m2。 roof were using cast-in-place reinforced concrete structure。
Mainly for the design of the structure scheme of transverse frame 6 axis seismic design。 In determining the frame layout, the structure is L-shaped, the deformation joint structure is pided into independent parts, hand selected a part of calculation。 And the gravity load calculation, and then transverse frame lateral stiffness calculation, and then according to the bottom shear method to calculate the horizontal seismic load size, after the earthquake and wind load under the internal forces (bending moment, shear and axial force) was calculated, and then calculate the vertical load (dead load and live load) under the action of the structure internal force, followed by a combination of internal forces and to identify the most disadvantaged group or a few Internal force combination。 Select the most secure calculation of the results of the reinforcement and drawing。
The entire structure in the design process, strictly abide by the relevant professional standard, reference to relevant information about the latest national standards, each link of the design of comprehensive scientific considerations。
Keywords : Frame structure, seismic design, Internal forces, Calculated reinforcement。
