Third, the structure overview
This project is a cast-in-place reinforced concrete frame structure, and the roof is a cast-in-place reinforced concrete slab. This project is located in the non-seismic fortification area, with the safety level of building structure as Grade II, the design level of foundation as Grade C, the construction quality control level of masonry structure as Grade B, and the structural design service life as 50 years.
1, foundation and foundation:
This project adopts independent foundation and pier foundation, with the moderately weathered tuff in the 4th floor as the bearing stratum, and the characteristic value of foundation bearing capacity is 2500Kpa. Independent foundation embedded in moderately weathered bedrock is not less than 250㎜, pier foundation embedded in moderately weathered bedrock is not less than 1000㎜. The length is determined according to the actual situation, and the reinforcing cage is longer. J 1 ~ J4 is an independent foundation under the column, and the rest are pier foundations. The strength grade of foundation concrete is C30, and the section size of foundation beam is 300×700㎜, 300×600㎜, 250×400㎜ and 250× 350 ㎜. C 15 plain concrete is used for foundation cushion concrete.
2. Main projects:
Beam section size: each floor has 250×600㎜, 250×500㎜, 300×700㎜, etc.
Column section size: column section is 400×500㎜, 350×500㎜, 500×600㎜, etc.
3, concrete strength grade:
The concrete strength grade of beams, slabs and columns adopts C30；;
4, steel bar and connection:
The raw materials are mainly HRB335(fy=300N/㎜2) and HPB225(fy=2 10N/㎜2) grade steel bars;
Covered electrode: E 4310-E 4313 is adopted for grade I reinforcement; Secondary reinforcement adopts e 5011-e 5014;
