According to local economic conditions to take, as well as norms designed to meet the public with the requirements of the economy, the domestic application. A total construction area of 2700, building height of , this works for the main frame structure, the intensity of seismic fortification levels to 7 degrees, of its serviceable life for 50 years. For the Group C of the residential construction, design consists of two parts: The first part is the construction of the graphic design, construction of the plane, elevation and profile design. The main building to solve the plane layout and design of legislation. The second part is divided into structural design, set beams, plates, in the section size. Calculate wind loads on each floor of the standard calculation, in the lateral rigidity, calculated under earthquake level of internal forces。(1)基本風(fēng)壓值:(2)基本雪壓值:地質(zhì)資料: ~。(4)凍土深度:本工程抗震設(shè)防烈度為7度。 會議室: ㎡。 陳列室: ㎡。(3)樓面構(gòu)造水泥樓面:10mm厚1:2水泥砂漿面層壓實抹光、15mm厚1:3水泥
