正常使用状态下的叠合楼板工程检测试验分析

Analysis of the Composite Floor Slab Engineering Tests Under Normal Use State

对既有个别楼板底部出现细微裂缝(非贯穿性裂缝),进行正常使用状态下的叠合楼板检测试验,以检测在正常使用状态下的挠度值及裂缝发展状况,尤其是板底修补后的部位。然后根据实测值,进行结构内力分析,并知该叠合楼板(带细微裂缝)结构承载力满足正常使用要求,可以在建筑工程中使用。

The individual crack appears at the bottom of the floor( not perfoliate crack),composite floor detection under the normal use of the experiment was carried out to detect in the normal service condition of deflection value and the development of cracks,especially the bottom parts after repairing. Then internal force of structure is analyzed according to the measured values,and it's know that the composite floor( with small cracks) structure bearing capacity meets the demand of normal use. So it can be used in the construction engineering.
