(清華大學(xué)土木工程系 北京100084)[提要] 介紹了8片低強(qiáng)度砂漿磚砌體經(jīng)鋼筋網(wǎng)砂漿抹面加固后的抗側(cè)力對比試驗(yàn)，其中面層厚度、加固面數(shù)和豎向壓力作為變化參數(shù)。試驗(yàn)表明，鋼筋網(wǎng)水泥砂漿抹面加固低強(qiáng)度磚砌體可以顯著提高墻體的水平承載能力和抗側(cè)移剛度。總結(jié)了加固參數(shù)對加固效果的影響，提出了適用于此類墻體加固的抗側(cè)力建議公式。
[關(guān)鍵詞] 鋼筋網(wǎng) 水泥砂漿 加固 磚砌體 極限荷載The contrast experiment of eight brick masonry walls with low strength mortar strengthened with steel-meshed cement mortar is introduced. Walls are different from each other because the parameters, such as thickness of cement mortar, side number of cement mortar and vertical load, are not exactly the same. The experiment result shows the strengthening method can notably improve horizontal ultimate load and the lateral stiffness of the walls. The effects of the strengthening are summarized and some practical formulas are concluded in order to solve the similar problems.
Keywords: steel-meshed; cement mortar; strengthening; brick masonry wall; ultimate load
