竹筋混凝土楼板的结构性能检验及评估

上世纪50年代末、60年代初,我国由于大量缺乏钢铁,不少建筑物用竹筋代替钢筋作为受力筋,制作小跨度混凝土构件,节省了不少钢材。目前,这批建筑物使用至今已近50a,接近钢筋混凝土结构的正常使用年限,因此,必须对这部分竹筋混凝土建筑物的结构性能进行重新检验和评估。以某高级中学教学楼为例,较详细介绍了竹筋混凝土结构性能检验方案的确定、检验数据的处理以及竹筋混凝土结构的性能评估等,以期对国内同类建筑物的性能检验与评估提供参考。

The Inspection And Evaluation of The Bamboo Contrete Structural Performance

In the late 1950＇s, the early 1960s, because of the lack of a large number of China＇s iron and steel, and many buildings using bamboo as a reinforcement to replace steel reinforcement force, the production of small-span concrete structures, saving a lot of steel.At present the use of these buildings has now operated for almost 50 years, close to ordinary reinforced concrete structure of the normal life span. Therefore, we must at this part of the structural reinforcement of concrete structures re-inspection and assessment. In this paper, a senior middle school buildings as an example, in more detail on the concrete structure of bamboo reinforcement of the inspection programme established, testing data processing and bamboo reinforcement of the concrete structure, such as performance evaluation. Similar to the domestic building inspection and assessment of the performance of reference.
