对在秸秆纸面草板表面复合无机面层形成的秸秆复合墙板进行了燃烧等级、2 h耐火极限测试,以验证其耐火性能。燃烧性能试验结果显示,秸秆复合墙板达到B1级难燃材料的要求,并且在燃烧增长率指数、600 s内总产烟量、烟气生成速率指数等指标方面均优于GB/T 9978.1—2008《建筑构件耐火试验方法第1部分:通用要求》的要求。对结合轻钢框架形成的双层秸秆墙体进行的2 h耐火性能试验显示,背火面平均温升仅17.5℃,背火面单点最高温升仅24.4℃,远低于标准规定的140℃的要求。经过2 h高达1050℃的高温燃烧,背火面基本保持原状,无破裂损伤,墙体未丧失完整性。 相似文献

建筑钢结构防火用石膏耐火板的研制与应用 总被引:2,自引:0,他引:2
根据我国近年建筑钢结构体系发展较快,但与钢结构建筑体系中墙体配套使用的墙体材料开发相对滞后的情况,北新集团新近开发了一种能与钢结构建筑墙体配套使用的耐火纸面石膏板和特种耐火板。该类板主要以建筑石膏粉与专用防火纸或玻璃纤维薄毡为主要原材料,通过适度发泡、促凝等工艺生产而成。板材既具有普通纸面石膏板优良的环保性能,其保温和耐火性能又比纸面石膏板有较大的提高。文章重点介绍了该板生产工艺、性能及与钢结构配套使用的节点处理、施工方法及建筑造价。 相似文献

用天然稻草或麦草为主要原料,经加热挤压成型,外表粘贴面纸而成的板材,称为纸面草板。主要用于建筑物的内隔墙、外墙内衬、吊顶板和屋面板等,它也可作外墙,但必须加可靠的外护面层。纸面草板属绿色建材产品。我国纸面草板工业虽从英国引进2条生产线,开了好头,有过快速发展的势头。但是困难和阻力重重,一直处在销售不畅,产量上不去的状态,已建成的纸面草板厂,除大洼一家厂勉强生产,其余均已停产,纸面草板行业进入低谷。近几年黑龙江省圣中(集团)股份有限公司在绥化建厂后,在积极推广。哈尔滨市双化建筑技术开发公司用纸面草板代替红砖建设各… 相似文献

自保温混凝土叠合承重墙可以解决长期存在的传统建筑外墙保温的难题。这种墙体通过内贴保温层(聚苯板)的混凝土预制板,再和现浇混凝土柱连接而成。该墙体具有整体性好、施工快、保温隔热性好等特性。在弹性阶段,预制板和隐形框架可很好的协同工作,形成一个整体;弹塑性阶段,预制板随着裂缝的开展而逐步退出工作;墙体最后退化为由预制板边肋和隐形框架组成的密柱叠合框架;预制板和隐形框架两者可形成两道抗震设防。因此自保温混凝土叠合承重墙体具有较大的承载力、良好的抗震性能和延性。 相似文献

It is a common practice to model multi‐storey tall buildings as frame structures where the loads for structural design are supported by beams and columns. Intrinsically, the structural strength provided by the walls and slabs are neglected. As the building height increases, the effect of lateral loads on multi‐storey structures increases considerably. The consideration of walls and slabs in addition to the frame structure modelling shall theoretically lead to improved lateral stiffness. Thus, a more economic structural design of multi‐storey buildings can be achieved. In this research, modelling and structural analysis of a 61‐storey building have been performed to investigate the effect of considering the walls, slabs and wall openings in addition to frame structure modelling. Sophisticated finite element approach has been adopted to configure the models, and various analyses have been performed. Parameters, such as maximum roof displacement and natural frequencies, are chosen to evaluate the structural performance. It has been observed that the consideration of slabs alone with the frame modelling may have negligible improvement on structural performance. However, when the slabs are combined with walls in addition to frame modelling, significant improvement in structural performance can be achieved. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

Experimental investigation of the influence of joint connection details between existing buildings and added new frames on failure mode of retrofitted slabs for the vertical expansion of old buildings: Part II 下载免费PDF全文
Jisoon Kim Won‐Kee Hong Yeo‐jin Yun 《The Structural Design of Tall and Special Buildings》2017,26(13)
Dismantling entire existing buildings can be circumvented by adding additional frames to provide more residence, thus avoiding the need to reconstruct buildings. The alternatives are to construct new frames on old apartment buildings in order to avoid entirely dismantling existing buildings. The conventional wall frames for super structures added onto existing buildings are replaced by frames consisting of composite beams and steel columns to minimize beam depth and weight of the load from the added frames. This paper studied joint connection types for the rehabilitation of old buildings to withstand lateral loads. Details of the joints between newly added steel columns and existing slabs are presented in this paper. The structural behaviors of anchored joints between the new 3‐story composite frames and an existing 15‐floor building were significantly investigated through extensive experiments. Complex failure modes were identified based on the test of the wall foundation types and the anchor types connecting the base plates to existing slabs. The authors previously reported that the flexural load‐bearing capacity of slabs was the dominant load‐resisting capacity. The column–slab joint connections introduced with experimental demonstrations in this study are expected to contribute to enhancing the lateral capacity of the extended buildings. 相似文献
