Before reconstruction, addition, structural alterations, or changes in the use of a building, and before increasing the load-bearing capacity, it is necessary to conduct a structural inspection of the building to evaluate the feasibility of altering the building's structure and usage functions, known as the structural and functional change inspection. When there are significant changes in function and structure, an earthquake resistance assessment is also required. Therefore, the structural and functional change inspection of the building, including the building inspection at Sheqi School, primarily focuses on the safety and earthquake resistance of the building under the condition of functional load changes.

Polymer patching mortar may encounter some unexpected situations in use, and among these, issues related to leakage should be paid attention to. Today, I will list them in detail for everyone.
Based on the actual conditions and in accordance with the current regulations, a rating is provided for the current safety status of existing buildings. The standards for assessing and rating dangerous buildings are as follows:
1. To ensure residential safety, establish this standard with a basis for the identification of hazardous buildings.
2. This standard applies to buildings managed and operated by real estate management departments. The identification of units' self-owned and private buildings may refer to this standard. This standard does not apply to industrial buildings, public buildings, high-rise buildings, and protected buildings.
3. The components mentioned in this standard refer to load-bearing components; the structures mentioned refer to systems composed of load-bearing components.
4. For important buildings or complex structures that are difficult to identify, necessary tests and calculations should be conducted.
5. When there are significant differences in factors that constitute dangerous buildings across regions, real estate management departments in each region may formulate specific implementation measures or supplementary regulations when enforcing this standard.

Frame structures are among the most commonly used structural forms, characterized by flexible architectural layout, ample usage space, ease of division, and good ductility. The decline in bearing capacity due to inadequate construction quality or excessive use年限 should not be overlooked, as it often leads to serious safety hazards. Below are key points to consider when dealing with frame structures; take a look.
Key Framework Structure Layout Points
Lateral load-bearing arrangement
The floor plan of houses usually has a shorter transverse dimension and a longer longitudinal dimension, with the transverse stiffness being weaker than the longitudinal stiffness. When the frame structure is arranged horizontally, it can to some extent mitigate the drawback of significant differences in the transverse and longitudinal stiffness of the house. Moreover, since the cross-sectional height of the connecting beams is generally smaller than that of the main beams, the window sizes can be designed larger, resulting in better indoor lighting and ventilation. Therefore, this structural arrangement is commonly used in multi-story frame structures.
Vertical load-bearing arrangement
In the vertical load-bearing frame structure, the floor load is transferred to the columns by the longitudinal beams. The height of the cross beams is generally small, resulting in a larger indoor net height and ease of passage along the longitudinal direction. Moreover, when the foundation is not uniformly distributed along the longitudinal direction of the house, the longitudinal frame can adjust this unevenness to some extent. A major drawback of the vertical frame load-bearing scheme is that the lateral stiffness of the house is low, thus this structural arrangement is rarely used in construction projects.
