（煤炭部杭州建筑設(shè)計研究院 310007）[提要] 針對當(dāng)前建筑市場對大空間底層框架磚房的超高設(shè)計需求，從規(guī)范要求出發(fā)，引進高層建筑中結(jié)構(gòu)轉(zhuǎn)換層的設(shè)計概念，提出了底層采用框架一剪力墻體系，來突破原有規(guī)范對底框磚房限制。并從一、二層結(jié)構(gòu)抗震承載能力相匹配的角度出發(fā)，初步討論了二層與底層的合理側(cè)移剛度比值的范圍，同時也討論了二層現(xiàn)澆鋼筋砼樓板的設(shè)計方法。
[關(guān)鍵詞] 框-剪結(jié)構(gòu) 轉(zhuǎn)換層 層側(cè)移剛度 比值 結(jié)構(gòu)抗震 承載能力 深梁At present, super-height brick-concrete buildings with the large-space and frame structure at first story are often required.ln order to avoid the limit of height by the Code of Building Aseismatic Design, the concept of transformation story from high-rise buildings and frame-shear wall on the first story is intro-duced. According to the coordination of the aseismatic capacity of the first and second story structure, the ratio of lateral stiffness between the second and first story and the design method of the cast-in-situ R.C: on the second floor are discussed.
Keywords: frame-shear wall; transformation story; ratio of lateral stiffness; aseismatic capacity; masonry construction; deep beam
