摘  要： 本設計是綜合大樓設計，位于縉云縣。總建筑面積約為3934㎡，底層占地面積約為768㎡，總高為22.8m，屬多層建筑。地震設防烈度為六度，抗震等級為四級；建筑結構安全等級二級，設計使用年限為50年，設計中不考慮抗震計算。本方案采用鋼筋混凝土現(xiàn)澆框架結構，主體結構為雙向承重框架。在進行荷載計算和構件截面估算后，選取一榀框架進行計算，用分層法算出內力，并對最不利荷載組合進行分析，通過D值法求出風荷載，進而進行框架梁柱截面設計。并選取部分樓面板、樓梯、雨蓬、樁基礎進行設計。本方案基礎形式采用樁基礎，樓梯為鋼筋混凝土現(xiàn)澆板式樓梯。整個方案設計基本符合設計和結構要求，具有一定的創(chuàng)造性和合理性。

Abstract: It is that the complex designs to originally design, located in JinYun country. The total construction area of about 3934 ㎡ and bottom covers about 768 ㎡, the total high is 22.8 m, is a multi-storey building. the earthquake intensity is six degrees to set up defences, the forth grade antidetonation,  Structural safety grade two and the design life span of 50 years. Design not consider seismic calculations. The program used cast-in-place reinforced concrete frame structure, the main load-bearing structure of the two-way framework. Conducting load calculation and after estimating beam, select a framework for load calculations, using layered calculated forces, later analysis the most unfavorable load portfolio ,through D value derived wind load, and then cross-section beams framework for the design. And select some floor panels, continuous beams, staircases, rain shelter valleys and gutters, the pile foundation design. This basic form is pile, the stair is the stair of cast-in-place modes in Chinese operatic music of armored concrete . The whole conceptual design accords with the design and structure demand basically, have certain creativity and rationality.
