钢框架混凝土筒体混合结构论文文献综述
马利平[1]（2017）在《高层型钢混凝土框架—混凝土筒体混合结构地震易损性分析》一文中研究指出随着现代建筑高度的不断增长,钢-混凝土混合结构也得到越来越广泛的应用。但是,钢-混凝土混合结构的抗震问题由于未经强震检测,目前研究还不充分。本文针对一30层的型钢混凝土(SRC)框架-钢筋混凝土(RC)筒体结构采用数值模拟和理论分析的方法,对结构的抗震性能及地震易损性进行分析研究。文章主要内容如下:首先,通过MIDAS/GEN有限元分析软件,验证了纤维梁柱单元模型分析简支梁构件的可行性。建立SRC框架-RC筒体结构有限元模型,其中型钢混凝土框架柱采用纤维柱单元,型钢梁及剪力墙分别采用MIDAS/GEN软件中提供的叁维梁单元和叁维剪力墙宏观单元。通过MIDAS/GEN有限元分析软件,对结构进行静力弹塑性(PUSHOVER)分析,并对该典型计算模型的抗震性能水平及对应的极限状态进行划分,以最大层间位移角作为结构不同性能状态的量化指标,进而确定其量化指标限值。通过PUSHOVER分析获得结构的能力谱曲线、地震需求谱曲线以及性能控制点,根据有限元分析所得数据进行结构的易损性分析。通过改变混合结构外部SRC框架刚度及内部RC核心筒刚度,对9个混合结构模型进行易损性分析,建立不同刚度体系下结构的易损性曲线,并将9个计算模型不同极限状态的超越概率曲线绘制在同一坐标系下,对比分析发现:结构各极限状态超越概率均随着结构刚度特征值的增加而减小,其中外部框架尺寸的改变相对核心筒剪力墙的改变对其刚度特征值影响较大,同时超越概率也发生较明显变化,结构整体趋于安全的概率增加较明显。再通过改变结构楼面活荷载达到改变型钢混凝土柱轴压比的目的,获得4个计算模型的易损性曲线,并将4个计算模型不同极限状态的超越概率曲线绘制在同一坐标系下进行对比分析发现:结构在逐渐趋于危险的过程中,轴压比的影响对于结构易损性的影响越来越明显,且随着轴压比的增加结构整体趋于安全的概率减小,趋于危险的概率增加,即其易损性逐渐增大。(本文来源于《西安科技大学》期刊2017-06-01）

储德文,梁博,王明贵[3]（2005）在《钢框架-混凝土筒体混合结构抗震性能振动台试验研究》一文中研究指出钢框架钢筋混凝土筒体结构在高烈度区的抗震性能和地震剪力在钢框架和混凝土筒体之间的分配比例是这种体系抗震性能研究的重点。模型的振动台试验表明,该结构体系的破坏集中于混凝土筒体,钢框架没有出现明显的破坏现象,结构整体的延性较好;而混凝土筒体结构承担了绝大部分的地震剪力。建议在混凝土筒体内预埋尺寸较小的构造用钢柱、钢梁,以改善筒体延性。(本文来源于《建筑结构》期刊2005年08期）
梁博[4]（2005）在《钢框架—混凝土筒体混合结构抗震性能振动台试验研究》一文中研究指出目前,钢框架—混凝土简体混合结构因兼具钢结构和混凝土结构两者的优点,在我国高层建筑中得到了广泛的应用。但是,国内外对该结构形式的抗震性能存在两个主要争议:钢框架-混凝土筒体混合结构是否是一双重抗震体系;如何调整钢框架的水平地震剪力。我国大部分地区处于地震区,有必要对该结构的抗震性能进行深入研究。 本文对一座12层钢框架—混凝土筒体混合结构1/10模型进行了模拟地震振动台试验,研究了该结构的抗震性能,包括:周期、阻尼动力特性;加速度、位移、层间位移动力反应;应变反应;混凝土筒体裂缝情况。试验表明钢框架可以起到第二道抗震防线作用,钢框架—混凝土筒体可以抵抗大震的作用而不倒塌,该结构形式具有较好的抗震性能。 本文根据试验数据,应用应变分析和侧移分析两种方法,着重研究了钢框架—钢筋混凝土筒体结构在各级地震作用下水平地震剪力在钢框架与混凝土简体之间的分配比例。得到了一些有用的结论,包括:钢框架、混凝土筒体和整体结构楼层地震剪力的比较;钢框架楼层地震剪力在小震、中震和大震作用下的变化规律;钢框架各楼层地震剪力与钢框架最大楼层剪力比值随震级变化规律;钢框架最大地震剪力楼层的剪力分担率随震级的变化规律。 本文通过振动台试验,针对钢框架—混凝土筒体混合结构抗震陛能的两个主要争议进行了研究,得出了一些有用的结论。本文最后提出了一些建议和对该研究领域的展望。(本文来源于《西安建筑科技大学》期刊2005-05-01）
王福智[5]（2004）在《考虑材料阻尼比不同的钢框架—混凝土筒体混合结构弹性时程分析》一文中研究指出随着现代建筑高度的不断增加,混合结构体系正在被逐步广泛的应用。但是目前国内对于钢框架-混凝土筒体混合结构的抗震研究的较少。由于混合结构是由两种完全不同的材料组成的结构体系,两种材料的阻尼比差别比较大,而实际工程设计中经常采用规范中的折算阻尼比的方法,折算阻尼比介于两种材料的阻尼比之间,这种方法是一种近似方法,其计算结果如应用于设计,与采用不同材料不同阻尼比的计算结果相比,有一定的差别。目前在这种混合结构日益普及的情况下,理论上对于材料阻尼差别对高层建筑反应影响的研究进行的很少。如果这种影响不加以重视,有时会形成很大的安全隐患,严重的会威胁到居民的生命、财产的安全。本论文首先用SATWE对一个实际钢框架-混凝土筒体工程进行建模,然后在SATWE中在不同的地震作用下对采用不同折算阻尼比的叁维立体模型进行弹性时程动力分析。本论文主要的研究内容是通过对上述工程实例用较精确的阻尼模型即钢框架和混凝土核心筒部分采用各自的阻尼比进行平面结构弹性时程计算,然后再对同一工程采用不同的折算阻尼比进行平面结构弹性时程计算,通过与较精确阻尼模型内力、位移结果的比较,判断折算阻尼比取值对计算结果的准确性的影响。最后对本结构折算阻尼比设计取值给出了建议。(本文来源于《天津大学》期刊2004-12-01）
