Seismic Design Standards for Buildings is a specification published and compiled by China Architecture & Building Press in 2010. What are the provisions of the seismic design standards for buildings in China? The following is the relevant content of the relevant building seismic design standards compiled by Zhongda Consulting:

Basic Overview of Building Seismic Design Standards:

Building Seismic Design Standards" This code is based on the requirements of the former Ministry of Construction's "Notice on Printing and Distributing (2006 Engineering Construction Standards and Specifications Formulation and Revision Plan (First Batch))" (Jian Biao [2006] No. 77), and is revised by the China Academy of Building Research in conjunction with the relevant Luliang metering, survey, research and teaching units on the "Building Seismic Design Code" GB 50011-2001.

In the process of revising the building seismic design standards, the compilation team summarized the experience of the Wenchuan earthquake in 2008, adjusted the fortification intensity of the disaster area, added the mandatory provisions on the construction requirements of the mountainous site, the frame structure filling wall, the masonry structure stairwell, and the seismic structure, and improved the requirements for the prefabricated floor structure and the elongation of the steel bar. Since then, we have continued to carry out special research and some experimental studies, investigated and summarized the lessons and lessons of the major projects at home and abroad in recent years, the new scientific research achievements of the first project, considered the economic conditions and engineering practice of our country, and widely solicited the opinions of the relevant design, survey, scientific research, teaching units and seismic management departments throughout the country, and finally reviewed and finalized the draft after repeated discussions, modifications, enrichments and trial designs.

The "Building Seismic Design Standards" mainly includes: (1) General Provisions (2) Terms and Symbols (3) Basic Provisions (4) Site, Foundation and Foundation (5) Seismic Verification of Functions and Structures (6) Multi-storey and High-rise Reinforced Concrete Houses (7) Multi-storey Masonry Houses and Bottom Frame Masonry Houses (8) Multi-storey and High-rise Steel Structure Houses (9) Single-storey Industrial Plants (10) Empty Houses and Large-span Roof Buildings (11) Civil, Wood and Stone Structure Houses.

When the building site is a category, the buildings of Category A and B shall be allowed to take seismic structural measures according to the requirements of the seismic fortification intensity of the region; Seismic structural measures should be allowed to be taken for Class C buildings according to the requirements of reducing the seismic fortification intensity of the region by one degree, but seismic structural measures should still be taken according to the requirements of the seismic fortification intensity of the region when the seismic fortification intensity is 6 degrees.

When the building site is class III and IV, the area with the basic acceleration of the design is and , in addition to the provisions of this code, seismic structural measures shall be taken according to the requirements of the seismic fortification category building with a seismic fortification intensity of 8 degrees (and 9 degrees) respectively.

Problems that need to be paid attention to when choosing a building site.

When selecting the construction site, a comprehensive evaluation should be made on the basis of the engineering needs and the relevant information of the first activity, engineering geology and first geology, and the favorable and unfavorable and dangerous sections for earthquake resistance. For unfavorable areas, avoidance requirements should be put forward; Effective measures should be taken when it is impossible to avoid it. For dangerous areas, it is strictly forbidden to build buildings of Category A and B, and buildings of Category C should not be constructed.

Legal analysis: The construction unit, the survey unit, the design unit, the construction unit, and the project supervision unit shall comply with the laws, regulations and mandatory standards for the seismic fortification of housing construction projects, ensure the quality of the seismic abrasion of the housing construction project, and bear the corresponding responsibilities in accordance with the law.

Legal basis: Regulations on the Management of Seismic Fortification of Housing Blind Wangshan House Construction Project

Article in the seismic fortification area engaged in the seismic fortification of housing construction projects related to activities, the implementation of the supervision and management of seismic fortification of housing construction projects, these provisions shall apply.

Article 3 The seismic fortification of housing construction projects shall adhere to the principle of giving priority to prevention.

1. The representative value of gravity load for the bottom layer is the weight of the column, wall and beam members from the upper part of the foundation to half the height of the second floor.

For the standard layer, it is the weight of the column-wall-beam member of the first floor.

For the top floor, it is the weight of the pillars, walls and beams of the roof (including insulation, waterproofing, protective layer, parapet, etc.) and the top half floor.

The above is very clear, so it is added according to the volume, the weight of reinforced concrete is 252, mainly according to the importance of the structure multiplied by different structural importance coefficients (it seems that it is not this name, and I can't remember what it is called), so as to strengthen the resistance of the structure to **.

Code for Seismic Design of Buildings [with Explanation of Provisions] GB 50011-2010 (with 2016 revision).

1 General Provisions.

1 0 1 In order to implement the national laws and regulations on construction projects, earthquake prevention and disaster reduction and implement the policy of focusing on prevention, so that the building can be fortified with earthquake resistance, reduce the damage of the building, avoid personnel, and reduce economic losses, this code is formulated.

The basic seismic fortification objectives of buildings designed according to this code are: when subjected to frequent impacts that are lower than the seismic fortification intensity of the region, the main structure can continue to be used without damage or repair; Damage may occur when subjected to a fortification equivalent to the seismic fortification intensity of the area, but it can still be used after general repairs; When subjected to rare** impacts that are higher than the seismic fortification intensity of the region, it will not collapse or cause serious life-threatening damage. Buildings with special requirements in terms of function or other aspects have more specific or higher seismic fortification objectives when designed with seismic performance.

Code 1 0 2 Buildings in areas with a seismic fortification intensity of 6 degrees and above must be designed for seismic resistance.

1 0 3 This code is applicable to the seismic design of construction projects in areas with seismic fortification intensity and 9 degrees, as well as the design of seismic isolation and energy dissipation and shock absorption. The basic methods specified in this code can be adopted for the seismic performance design of buildings.

The seismic design of buildings in areas with seismic fortification intensity greater than 9 degrees and industrial buildings with special requirements in the industry shall be implemented in accordance with relevant special regulations.

Note: "6 degrees, 7 degrees, 8 degrees, 9 degrees" in this specification is the abbreviation of "seismic fortification intensity is 6 degrees, 7 degrees, 8 degrees, 9 degrees".

1 0 4 The seismic fortification intensity must be determined in accordance with the documents (drawings) approved and issued by the authority stipulated by the state.

1 0 5 In general, the seismic fortification intensity of the building should be determined according to the first basic intensity of China's first dynamic parameter zoning map (the intensity value corresponding to the basic ** acceleration value of the design of this code).

1 0 6 The seismic design of the building shall not only meet the requirements of this code, but also comply with the provisions of the current national standards.

1. The width of the earthquake-proof joints of the frame structure (including the frame structure with a small number of earthquake-resistant walls) should not be less than 100mm when the height does not exceed 15m; When the height exceeds 15m, the width of 6 degrees, 7 degrees, 8 degrees and 9 degrees should be increased by 20mm for each additional height of 5m, 4m, 3m and 2m respectively;

2. The width of the earthquake-proof joint of the frame-seismic wall structure house shall not be less than 70 of the value specified in item 1) of this paragraph, and the width of the shockproof joint of the earthquake-resistant wall structure house shall not be less than 50 of the value specified in item 1) of this paragraph; and should not be less than 100mm;

3. When the structure types on both sides of the shockproof joint are different, it is advisable to determine the width of the joint according to the type of structure that requires a wider shockproof joint and the lower house height.
