The building curtain wall's wind load resistance, air tightness and water tightness test results fail to meet the standards, posing a safety hazard.

As a key component of the building envelope, the wind load resistance, air permeability and watertightness of architectural curtain walls directly affect building safety and occupant comfort. In accordance with GB/T 21086 and JGJ 102, architectural curtain walls shall undergo physical performance testing as required by the design. Curtain wall performance failures mainly fall into three categories: insufficient wind load resistance, poor air permeability and poor watertightness. Analyzing the root causes, designers typically reference the basic wind pressure values and shape coefficients in GB 50009 directly when calculating curtain wall wind loads, without considering the special wind environment of the building's location. For super high-rise buildings and buildings with complex geometries, wind tunnel test results are the most reliable method for determining design wind loads, but many projects skip wind tunnel testing to save costs. Regarding materials, some projects use aluminum alloy profiles with insufficient wall thickness or connecting bolts of substandard grade. Regarding construction, the installation quality of connection nodes fails to meet design requirements. From an operational impact perspective, the direct risk of substandard curtain wall performance is reduced building safety. In 2023, after a typhoon in a coastal city, glass curtain walls of multiple high-rise buildings exhibited panel cracking and operable sash detachment. From a maintenance perspective, buildings with substandard curtain wall performance require substantial annual maintenance expenditure for inspection and repair. The core measures to address such issues include conducting wind tunnel tests for buildings exceeding 100 meters in height or with complex geometries, reviewing the load-bearing capacity of critical curtain wall connection nodes, establishing a material incoming inspection system for curtain walls, and commissioning qualified testing agencies to conduct physical performance testing after curtain wall installation is completed. From the systems engineering perspective of engineering management, resolving this issue requires the coordinated advancement of four dimensions: institutional design, process control, technical support and cultural development. At the institutional design level, clear responsibility boundaries and operating procedures must be established, translating code requirements into executable job responsibilities and work standards. At the process control level, full-lifecycle quality supervision and dynamic correction must be implemented to ensure that the work results at each stage meet expected objectives. At the technical support level, information-based methods and intelligent tools should be actively introduced to improve management precision and efficiency. At the cultural development level, quality awareness and compliance awareness must be cultivated among all personnel to foster an organizational atmosphere that pursues excellence. Only by organically integrating these four dimensions can the recurring quality defects and management challenges in engineering construction be fundamentally resolved, achieving continuous improvement and excellence in project management.
