钢结构的基本原则
钢结构设计必须遵循以下基本原则：安全性、经济性和可靠性。安全性要求钢结构在各种作用力作用下能够保证使用中的稳定性和耐久性能；经济性要求通过合理的材料选择、加工方式以及施工技术来降低总体成本；可靠性要求设计方案能够确保工程在预期寿命内正常运行，且在发生异常情况时能迅速恢复到正常状态。
钢材的选择与验收
steel material selection and inspection, steel materials used in structural design must meet the specified strength grade requirements, and shall be inspected according to relevant standards before use. The inspection items include chemical composition, mechanical properties, size tolerance, surface quality and other aspects.
结构形式与尺寸计算
structural form & dimension calculation, the choice of structural form is based on the load type and distribution characteristics of the structure. For example, for a simple frame structure with vertical loads mainly acting on it, a single-layer or multi-layer frame can be adopted; while for structures with complex load conditions or large span requirements such as roofs or bridges, more advanced forms like arches or cable-stayed systems may be preferred.
施工技术与质量控制
construction technology & quality control measures should be taken during construction to ensure that all components are installed correctly and meet the design specifications. Quality control includes regular inspections during construction process to check whether welding quality meets standards; whether bolt connections are tight enough; whether concrete has reached required strength levels.
工程验收与维护管理
engineering acceptance & maintenance management after completion of the engineering project's construction work shall undergo thorough inspections by designers and engineers to verify compliance with design specifications and regulations before being accepted by users. Maintenance management involves establishing an ongoing maintenance plan including regular inspections for potential defects or damage caused by aging over time.
