What are the principles and main points of the seismic design scheme of civil buildings? ? (1) Select sites and foundations that are favorable for earthquake resistance. (2) Comprehensive planning to avoid secondary disasters during earthquakes. (3) The plane layout of the engineering building should be regular and symmetrical, the centroid and the center of gravity should be as close as possible, and should have good integrity. (4) The façade and vertical section of the engineering building should be regular, the lateral stiffness of the structural features should be uniformly changed, and the mass of the engineering building should be uniformly distributed. (5) Select a technically better and economically reasonable seismic structure characteristic system. (6) Reduce the weight of the building and its center of gravity. (7) Ensure the integrity of structural features and further strengthen structural processing. Increase the number of ring beams and structural columns to further strengthen the integrity of the connection between components. The connection between structural components such as stairs, parapets, overhangs, balconies, decorative veneers and adjacent components should be sufficiently safe and reliable. sex. At the same time, the structural design must meet the requirements of the relevant specifications. For example, when the structural parts are connected, the anchorage length of the building steel bars should meet the requirements of the relevant specifications; the strength of the building steel bars should meet the requirements of the relevant specifications; the elongation performance indicators of the building steel bars should meet the requirements of the relevant specifications to ensure that the earthquake There is no brittle fracture failure of building steel bars. Is the foundation condition related to the earthquake resistance of engineering buildings? Better foundation conditions are the key to earthquake resistance of engineering buildings. In particular, the foundation conditions of high-rise buildings must be good, the bearing capacity must be large and the deformation must be small. Expansive rock and soil as the foundation is very destructive to the building, because it is easy to expand and shrink and deform, so it often causes the building to rupture. For the foundations of ancient river floodplains, depressions, coastal shallow seas, and newly deposited uncompact sandy soils and low-plastic clays, under the action of strong earthquakes, liquefaction phenomena such as sand gushing and mud leakage may occur, resulting in serious damage to housing construction. collapse. How to improve the seismic performance index of high-rise buildings? How to improve the seismic performance index of high-rise buildings in the city is a more important and complicated problem. An expert from the University of Colorado pointed out:“It was the buildings that caused the casualties, not the earthquake.”It can be seen that how to improve the seismic performance index of urban buildings will be the key to reducing the damage of natural disasters. Today's biologists have designed seismic systems for building structures with various structural characteristics, such as trying to separate the building and the foundation with rubber and lead objects to support the base and so on. There are also news reports that experts have designed a network of sensors and computers. When an earthquake occurs, the sensor transmits vibration information to the computer, and the computer sends out instructions to adjust, so that the building moves in the opposite direction of the vibration. The building can save or reduce losses. When the Ruguijinshan earthquake occurred, the skyscrapers swayed violently, sometimes as much as 06-09 meters, but they were still safe. Is the house we live in safe? According to the National Seismological Network, at 14:28 on May 12, 2008 Beijing time, an earthquake of magnitude 8.0 occurred in Wenchuan County, Sichuan Province (31 degrees north latitude, 1034 degrees east longitude), and Beijing, Chongqing, Shanxi, Shaanxi, Hubei, Hunan, The earthquake was felt in Shandong, Henan and other places. After the earthquake, a wide range of urban residents are concerned about how many earthquakes the house we live in can resist. Is the house we live in safe? At this stage, according to relevant national laws and regulations, residential buildings in most areas should have the ability to defend against earthquake damage with an intensity of 6-8. Therefore, the shock brought by the Wenchuan 8.0-magnitude earthquake to Beijing this time is completely within the residential seismic capacity. Which building structure is more earthquake resistant? While meeting the earthquake-resistant building standards, people are more concerned about which building structure is safer in the event of an earthquake? At present, the main structural forms of residential buildings are: brick-concrete structure, reinforced concrete structure, light steel structure, and wood structure that only appears in villa projects. In terms of seismic standards, the houses of these structures should meet the requirements of seismic fortification intensity in corresponding areas in accordance with the norms and standards of the Ministry of Construction. However, in terms of seismic performance, cast-in-place reinforced concrete structures are superior to prefabricated structures; light steel structures and wood structures are also structural forms with better seismic performance. Generally speaking, for houses of the same earthquake resistance level, low-rise buildings are better than high-rise buildings. In low-rise buildings, the use of light steel structure is more suitable for earthquake resistance!
