摘要

对南昌市政府行政中心的建筑、结构、施工等进行了设计。结构部分选取④号轴线框架进行详细设计。采用迭代法计算竖向荷载作用下的内力(弯矩、剪力、轴力),采用底部剪力法和D值法计算水平荷载作用下的内力。内力组合后,选取最不利的内力值进行框架结构的配筋计算,并绘制了框架平法施工图和传统配筋图。进行了基础及主体框架工程量计算,编制了施工进度横道图,并绘制了施工平面布置图。 关键词:建筑,框架,结构设计,施工组织 II

Abstract Design of architecture, structure and construction for The Hall administrative center of N Nanchang City was performed in the current work. Framework of the fourth axes was chosen for the detailed structural design. Internal forces such as bending moment, shear and axial force of the framework under vertical loads were calculated by iterative method. Equivalent base shear method and D-value method were utilized for the calculation of internal forces of the framework under the horizontal loads. After combination of the internal forces, the most unfavorable combinative internal force was chosen for the steel bar calculation. Construction general plan drawing and traditional reinforcement drawing of the designed framework were also presented. The amounts of the foundation and the main framework were calculated. The bar graph schedule and the construction layout were also given. [KEY WORDS]:Architecture, framework, structural design, construction organization
