Both systems are used in industry
Steel frames and reinforced concrete frames are both common for warehouses, workshops and industrial buildings. The better choice depends on the project, not on the material in general. The questions below usually decide the outcome.
钢框架与钢筋混凝土框架都常用于仓库、车间与工业建筑。哪种更合适取决于具体项目,而不是材料本身。下面的问题通常决定结果。
Questions that decide the choice
- Clear span: do you need long column-free space for storage racks, production lines or vehicle movement?
- Schedule: is there a fixed date by which the building must be usable?
- Local resources: are cement, aggregate, rebar and experienced concrete contractors available near the site?
- Import logistics: is the route for imported components already organised, including port and inland transport?
- Fire and process: what fire resistance does the process or the stored material require?
- Vibration: will heavy vibrating equipment be installed, and does it need isolation?
- Later changes: is extension, relocation or modification expected during the building's life?
- Environment: humidity, salt spray or chemical exposure determine the protection system required.
净跨度:是否需要大跨度无柱空间用于货架、生产线或车辆通行。工期:是否有必须投入使用的确定日期。当地资源:现场附近是否可获得水泥、骨料、钢筋与成熟的混凝土施工队伍。进口物流:进口构件的运输路线(含港口与内陆运输)是否已组织好。防火与工艺:工艺或存放物料对耐火性能的要求。振动:是否安装重型振动设备并需要隔振。后期改动:使用期内是否可能扩建、搬迁或改造。环境:湿度、盐雾或化学介质决定所需的防护体系。
Combining the two
Hybrid solutions are common: a steel frame with concrete floors, or concrete columns with steel roof trusses. The combination is chosen to suit the load path, the fire requirement and the construction sequence.
组合方案也很常见:钢框架配混凝土楼板,或混凝土柱支承钢屋架。组合方式按传力路径、防火要求与施工顺序确定。
Comparing offers fairly
If you are deciding between the two systems, ask for both to be priced on the same scope, the same code and the same exclusions. Only then does the comparison reflect the real difference.
若在两种体系之间选择,请要求按相同供货范围、相同规范与相同不含项分别报价,比较结果才有意义。
