High rise building construction settlement observation, single storey building needs to do settlemen

The formula is simple, but it is not easy to process so much data.

I recommend you to do it with software, just import the raw data.

Horizontal settlement analysis software.

Does a single-storey building need to do settlement observation? Hello, I am glad to answer for you<> pro-single-storey steel structure generally does not need to do "building settlement observation record", but there are special requirements of single-storey steel structure need to do "building settlement observation record" construction engineering, whether it is a single floor or a high-rise to do settlement observation points for settlement observation, in the construction drawing design has been considered and given to set the location of the settlement observation point. Where the design of buildings and structures with more than one floor requires the setting of observation points, artificial, land foundation (sand foundation), etc., should be set up for subsidence observation, and the construction should be observed and recorded on schedule or according to the progress of the layer until completion.

1. The setting of the horizontal base point: the setting of the base point is based on the principle of ensuring its stability and reliability, and it should be set on the bedrock or on the soil layer with low compressibility. The location of the level base point should be close to the observation object, but it must be outside the influence range of the pressure generated by the building.

2. The setting of observation points: the layout of observation points should be able to fully reflect the deformation of the building and be determined in combination with geological conditions, and the number should not be less than 6 points. 3. Precision level and steel level should be used for measurement, and the first observation object should be fixed with measuring tools and fixed time measuring personnel, and the instrument should be strictly calibrated before observation.

4. The measurement accuracy should be measured at the level of level, the length of the line of sight should be 20 30m, the height of the line of sight should not be lower than the observation of the meteorological data, and the number and time of observation should be determined according to the specific building. When the foundation pit is deep, the rebound observation after excavation can be considered. Extended material: I hope mine can help you <>

Do you have any other questions?

The allowable amount of settlement observed in buildings is millimeters.

The allowable amount of settlement observed in buildings is millimeters. If it is reasonable to be in such an area, the house will be relatively stable. However, if it exceeds this range, it is necessary to determine its compressibility according to the specific conditions of different soil types, and combine it with the time relationship curve to be able to judge quickly, and it is necessary to master the relevant accuracy.

Specification for building settlement:

For deep foundations or high-rise and super high-rise buildings, the load of the foundation should not be missed, and the observation points should be laid and observed from the foundation floor. According to the information provided by a design institute, if only the observation point is placed on the ground floor of the building, the load of 5t m2 (about equal to three floors) will be missed, which will affect the overall analysis of deformation. Therefore, the settlement observation of this kind of building should start from the time of foundation construction to obtain the settlement of the foundation mu and the superstructure.

If it belongs to the following buildings, deformation observation should be carried out during construction and use:

1) The foundation of the hall is designed as a grade A building;

2) Buildings with a design grade of B on composite foundation or weak foundation;

3) Expansion of buildings with additional floors;

4) Buildings affected by the excavation construction of adjacent deep foundation pits or affected by changes in environmental factors such as groundwater on the site;

5) Projects that need to accumulate construction experience or conduct design reverse analysis;

Buildings with more than 14 floors or more than 14 floors or complex shapes;

7) Large and important buildings and structures.

If the project is obviously a foundation design and refers to a building with a deficit level of C (such as a 6-storey residential building with good foundation conditions), settlement observation is not required.

If you can't determine the design grade of the foundation, or if you have any doubts, please ask the design unit to clarify whether settlement observation is required, and please reply in writing or write it into the drawing review record. ,6,
