The structure of this design uses the reinforced concrete frame structure. The frame structure is characterized by beam column load bearing, the wall only separates, the retaining function, the room arrangement is more flexible. Natural conditions are as follows: basic wind pressure: 0.55kN/m2 (return period is 50 years); basic snow pressure: 0.20kN/m2 (return period is 50 years); local area of the basic earthquake intensity is 7 degrees; earthquake is grouped into the first group; site classification as type IV; according to the height of the building and fortification intensity, seismic level of this building is three. Geological conditions and geological assessment of the site are as follows: the bulk density of soil is calculated according to 18kN/m3, and the vertical distribution and the main physical and mechanical indexes of the soil are the geological prospecting report..
Main materials: strip foundation under wall, single column using C30, plain concrete cushion C20. Frame column, beam, plate, stairs C30 concrete pouring. The HPB335 grade steel stirrups, beams and columns made of HRB400 steel. Steel, steel, steel Q235B or Q345, welding rod: according to the JGJ18-2003 welding and acceptance procedures, the third chapter of the use of. Structural column, wall beam, horizontal filling wall opening frame, capping cast-in-place lintel, grade of concrete strength by C20. The parapet exposed cast-in-place component and not marked by C30 concrete pouring.
