应县木塔结构变形现状及分析

为了解应县木塔的构件变形和整体变形现状,对其圆柱的柱头和柱脚坐标、阑额和乳栿的挠度、楼板的相对高程进行了现场测量和分析,得到了圆柱倾斜水平投影值和柱脚高程、内外槽高差、阑额和乳栿的挠曲程度和整体变形等几何参数和力学特征。结果表明:在构件变形层面,应县木塔二层明层和三层的圆柱倾斜最严重,四层平坐层和五层平坐层外槽南侧、西南侧和北侧的圆柱倾斜水平投影值较大,木塔向东北向的倾斜仍在加剧;柱脚呈现出南高北低的规律,内、外槽高差从二层明层往上依次减小;除四层明层和五层明层外,其他各层均有25%~35%的阑额挠度过大,需要进行替换或加固,乳栿挠度相对较小;木塔的整体变形在东西向和南北向存在显著差异,从二层平坐层至五层明层,东西向各层中心偏移值先增大后减小,南北向各层中心偏移值逐层递增;二层明层到三层明层外槽柱向东的中心偏移量占木塔在该方向整体倾斜偏移量的75%,二层明层外槽柱向北的层位移占木塔在该方向整体倾斜偏移量的42%,各层中心偏移方向也存在差异。

考虑墙体影响的青城山灵官殿动力特性及地震响应分析

中国西南地区的山地古建筑众多,因其具有柱底不等高约束、抗侧刚度不均匀等结构特征,与平地上古建筑的抗震性能不同.为研究山地古建筑木结构的动力特性和地震响应规律,以青城山灵官殿为研究对象,对结构进行原位动力特性测试,获得其模态参数,并建立无墙体和有墙体数值模型,将有墙体模型的自振频率模拟值与实测值进行对比以验证数值模型的正...     

再生混凝土空心板的抗弯承载力实验

再生混凝土空心楼盖作为一种新型结构有着很大的优越性,现浇混凝土空心楼盖结构具有自重轻、提高空间利用率、减少钢筋用量、抗震性能好、隔音性能优、综合造价低且施工工期短等优点,适用于大跨度、大空间的多高层建筑,能获得很大的使用空间和经济效益.为了研究将再生混凝土应用到空心楼板中的可能性,本文中设计了4块再生混凝土空心板,完成了静力实验,分析了不同再生混凝土粗骨料取代率对空心楼板承载力、裂缝、挠度的影响.     

Factors Affecting the Rent of Shops in Commercial Complexes: A Case Study of Shenzhen Shekou Sea World

The rent of shops in commercial complex reflects consumers' preferences to some extent, and provides references for urban planning and the construction and operation of commercial complex. In this paper, Sea World Commercial Complex in Nanshan District of Shenzhen City is taken as the research object, and correlation and variability analysis on 41 groups of shop data are conducted. It is found that rent of shops in the same commercial complex is affected by location, visibility and area of outdoor stall, while the influence of shop area on rent is not obvious. Additionally, there is no significant correlation between the accessibility to traffic stations and the rent of shops in pedestrian business district.     

Modelling a whole building stock: domestic,non-domestic and mixed use

ABSTRACT

Work on energy use in buildings – in university research, professional practice and government – has tended to draw a broad distinction between ‘the domestic stock’ and ‘the non-domestic stock’. A further tendency has been to focus attention on types of non-domestic buildings devoted to single uses (e.g. offices, shops or hospitals). This paper reports an empirical research programme in which the complete building stock in large areas of England and Wales is comprehensively represented in great detail, using a new method and model called 3DStock. The model breaks down activities by floor level and within each floor of every building. The results show that the extent of mixing of uses is much greater than has previously been acknowledged, especially towards the centres and in the older parts of towns and cities. These mixed-activity buildings are sometimes relatively simple combinations of domestic and non-domestic, e.g. urban retail with flats above, while others are complex mixtures of different non-domestic activities. The model can be used to investigate how these complex relationships influence energy use. It is argued that, at the larger scale, explicit account needs to be taken of the mixing of uses in future stock models for research and policy-making.

四边简支现浇混凝土空心楼盖二次抗火性能试验研究

为探究火灾后采用聚合物砂浆加固修复混凝土空心楼盖二次火灾下的抗火性能,对四边简支混凝土组合塑料模盒空心楼盖进行两次火灾试验。介绍了试验空心楼盖第一次受火试验及火灾后构件修复情况,重点介绍了加固修复后空心楼盖第二次火灾试验,描述了试验空心楼盖在两次受火下的破坏特征、变形和温度场分布规律,并进行分析和对比。研究结果表明:采用聚合物砂浆修复的空心楼盖在二次火灾作用下,第一次火灾受损较为严重的部位易产生爆裂脱落,从而降低了耐火极限;二次受火下楼盖内混凝土的温度峰值高于一次受火,且距离板底越近,两次火灾作用中温度峰值差值越大;试件在两次火灾作用下跨中处最大竖向位移基本相同,第二次受火作用后的残余位移小于第一次;采用聚合物砂浆对火灾后的空心楼盖进行修复,修复后的楼盖仍具有一定的抗火性能。     

华安县“五馆一中心”复杂结构设计

华安县"五馆一中心"由东、西两个单体组成,各馆之间通过2层连廊和平台连接,各馆设1层地下室。项目场地南北高差9m,北侧室外地面在建筑地上2层楼面附近,南侧室外地面在地下室底板面。本工程结构设计存在建筑高度的判定、嵌固端的选择、结构设缝、南北侧土推力不平衡等问题;由于文体建筑的功能需要,主体结构存在平面不规则、竖向不规则、斜柱、穿层柱等多个不规则项。从结构体系和概念的角度,界定了建筑高度和嵌固端,进行了计算模型的简化,对关键构件进行性能化设计,对关键节点进行有限元分析,确保结构安全可靠。研究结果可为坡地建筑的超限结构设计提供参考。
