【摘要】：改革開(kāi)放30多年來(lái),隨著國(guó)家經(jīng)濟(jì)飛速發(fā)展,城市的建筑如雨后春筍大批建成；但是我國(guó)是一個(gè)多地震國(guó)家,尤其是近十年以來(lái)的地震給人民生命和財(cái)產(chǎn)造成很大的損失；2008年汶川大地震后,國(guó)家比較修訂了抗震規(guī)范,也要求各省市對(duì)學(xué)校主要教學(xué)樓進(jìn)行檢測(cè)鑒定,對(duì)不滿(mǎn)足抗震規(guī)范要求的建筑結(jié)構(gòu)進(jìn)行加固,以保證學(xué)生的生命安全。本文針對(duì)某學(xué)校一棟教學(xué)樓,進(jìn)行了檢測(cè)、鑒定和抗震加固設(shè)計(jì),為同類(lèi)工程的抗震加固提供一些參考。本文首先綜述了國(guó)內(nèi)外對(duì)鋼筋混凝土框架結(jié)構(gòu)進(jìn)行檢測(cè)鑒定及常用的加固方法。然后,對(duì)某單位鋼筋混凝土框架結(jié)構(gòu)的教學(xué)樓進(jìn)行了檢測(cè)與鑒定,分析了各種加固方案的優(yōu)缺點(diǎn),設(shè)計(jì)了綜合的加固方案：對(duì)于平面不規(guī)則之處,采用增加鋼筋混凝土梁板的方法來(lái)增加結(jié)構(gòu)的平面剛度；根據(jù)不同位置框架柱,分別采用加大截面法、外包鋼加固法、外包鋼和加大截面綜合的加固法�？蚣芰旱募庸谭椒ú捎猛獍摲ê图哟蠼孛娣�。樓梯間磚墻采用鋼絞線(xiàn)網(wǎng)-Ⅰ級(jí)聚合物砂漿抹面加固。通過(guò)上述加固設(shè)計(jì),使原結(jié)構(gòu)滿(mǎn)足現(xiàn)行抗震規(guī)范要求。
[Abstract]:Since the reform and opening up for more than 30 years, with the rapid development of national economy, urban buildings have been built in large numbers, but China is a multi-earthquake country, especially the earthquake in recent ten years has caused great losses to people's lives and property. After the Wenchuan earthquake in 2008, the country has revised the seismic code comparatively, also requires each province and city to carry on the inspection appraisal to the school main teaching building, carries on the reinforcement to the building structure which does not meet the seismic code request, in order to guarantee the student's life safety. In this paper, a teaching building in a school is tested, identified and designed for seismic reinforcement, which provides some references for the seismic reinforcement of similar projects. This paper first summarizes the inspection and appraisal of reinforced concrete frame structure and the common reinforcement methods. Then, the paper tests and appraises the teaching building of a certain unit reinforced concrete frame structure, analyzes the advantages and disadvantages of various reinforcement schemes, and designs a comprehensive reinforcement scheme: for the irregular plane, The method of adding reinforced concrete beam and slab is adopted to increase the plane stiffness of the structure, and according to the different position of frame column, the method of increasing section, the method of steel reinforcement, the method of reinforcing steel and the method of comprehensive strengthening with increasing section are adopted respectively. The reinforcement method of frame beam adopts the method of encased steel and the method of increasing cross section. The masonry wall in the stairway is strengthened with steel wire mesh-grade I polymer mortar. Through the above reinforcement design, the original structure can meet the requirements of the current seismic code.
