钢筋混凝土框架结构受非正常高温后的检测与加固

The Detecting and Strengthening Method in Armored Concrete Frame under the Condition of the Abnormal Heat

钢筋混凝土框架结构受非正常高温后(超过200℃),混凝土将出现强度降低,混凝土表面脱落,有效断面减小,构件会出现不同程度变形。对梁、柱受非正常高温后通过检测,有针对性地提出加固方案。

Reinforced concrete structure under the condition of the abnormal heat （over 200℃）, its strength will become lower;concrete surface will fall off; useful- area decreases and the component will be deformed in different level. Through test for beam ＆ pillar under the condition of the abnormal heat, we propound a strengthening project.
