河北房屋加固混凝土柱的加固中，有多種加固方式可供選擇，其中比較有代表性的分別是增大截面加固法、外粘型鋼加固法、碳纖維布加固法，三種方法各具特色，在加固時需根據具體情況進行選擇。

1、增大截面加固法通過增加結構截面面積與配筋來提高結構承載力，其使用經驗豐富，在梁、板、柱上均有較廣泛的應用。在混凝土加固中，增大截面法尤其適用于因柱體截面較小導致承載力不足的情況。為使增大截面法在混凝土中達到最佳的加固效果，需要保證混凝土基材強度等級不能低于C13，加固用受力鋼筋不應小于14mm，同時種類、截面形式、受力情況不同的混凝土柱，需要采用不同的構造形式。

河北房屋加固碳纖維布加固效果較好、幾乎不增加自重且施工方便，但不適用于小偏心受壓構件，且對軸心受壓構件加固中，還需注意柱體長細比與截面是否滿足要求。因此在選擇碳纖維布加固前，需要對混凝土柱有較深的了解，以避免不滿足碳纖維布加固前提。
