The design standard of green buildings in Jiangsu Province is formulated to standardize and improve the construction level of green buildings in Jiangsu Province. Jiangsu province green building design standard is applicable to the green design of new, rebuilt and expanded civil buildings in Jiangsu province. Among them, what are the requirements of Jiangsu green building design standards for the main structure design? The following is an introduction to the requirements of Jiangsu green building design standards for the main structure design brought by the construction network for reference.

The new building can appropriately increase the design load value of the structure.

the structural layout should improve the adaptability to the architectural layout.

the structural scheme should follow the basic principle of seismic conceptual design, and serious irregular structural scheme should not be adopted; For particularly irregular structures, corresponding technical measures should be taken and the seismic performance target should be determined.

on the premise of ensuring safety and durability, reasonable structural scheme and component design should be adopted in structural design to reduce material consumption. Structural design should meet the following requirements:

1. It is not suitable to adopt structures that are difficult to implement and structures that are out of code due to irregular building shapes;

2. The structural system with less material consumption should be selected according to the mechanical characteristics;

3. Class-A buildings give priority to isolation or energy dissipation structures; Class b and class c buildings should adopt isolation or energy dissipation structures when conditions permit;

4. In high-rise and long-span structures, steel structure, steel and reinforced concrete mixed structure system should be adopted reasonably.

5. The vertical members of high-rise concrete structures and the horizontal members of long-span structures should be optimized in cross section;

6. For long-span concrete floor structures, bonded prestressed beams, unbonded prestressed concrete floors, cast-in-place concrete hollow floors, sandwich floors, etc. should be adopted reasonably;

7. For steel structure members controlled by strength, high-strength steel should be preferred; For steel structures controlled by stiffness, priority should be given to adjusting the arrangement of members;

8. components with obvious material saving effect and high industrial production level should be reasonably adopted.

The foundation optimization design can consider the collaborative analysis and design of foundation and meet the following requirements:

1. High-rise buildings should consider the * * * interaction between foundation and superstructure for collaborative design.

2. When controlling the settlement of pile foundation, the synergistic effect of pile cap, pile and soil should be considered.

3. The raft foundation should be optimized according to the calculation results of pile, soil and * * *.

Post-grouting technology should be adopted for bored piles to improve side resistance and end resistance.
