砌体结构抗震设计中小开口墙的刚度计算

本文对砌体结构抗震设计中小开口墙刚度按剪弯变形法计算进行了分析。提供了一个近似小开口培刚度影响系数β的表格，可直接进行小开口墙刚度的计算。本文提出的简化计算方法快捷方便，有较大实用价值。

富田古村传统住宅外墙开口特征与生态适应性研究

运用建筑类型学、建筑美学、建筑生态学等理论,采用分类归纳、案例说明、原理分析的方法,对富田古村传统住宅外墙开口(包括门、窗、通风孔)的特征及生态适应性进行研究。研究结果表明其开口的构成、类型、形式、材料、构造、装饰、分布等方面独具特色;在就地取材、采光、通风、遮阳、防水等方面体现了生态适应性。对现代生态建筑设计及传统建筑文化的研究具有一定的参考价值。

具有上部侧墙开口和顶部开口的大空间建筑室内热环境特性的比较

针对具有上部侧墙开口和屋顶顶部开口两种上部开口形式的大空间建筑,模拟了采用分层空调时不同工况下的室内温度场和速度场,分析了两种上部开口形式下喷嘴高度,上部开口面积、排风温度和排风量对室内热环境的影响。

开圆形洞口整体墙和小开口整体墙的研究

为了研究开圆形洞口整体墙和小开口整体墙,采用圆形洞口与正方形洞口进行对比分析。分别将圆形洞口等效为边长为直径的正方形、等面积正方形和圆内接正方形对比顶点位移。结合有限元分析和理论分析,采用圆内接正方形作为等效矩形截面,进行惯性矩计算;采用无洞口的横截面面积乘以洞口削弱系数,进行截面面积计算。

低碳建筑在方案阶段的自然通风模拟设计

在方案设计阶段,合理的建筑设计可充分挖掘自然通风潜力,最大限度地利用当地气候资源,对实现低碳建筑设计具有重要意义。针对重庆市某拟建节能办公建筑,应用PHOENICS软件重点对该建筑不同外墙开口和内部隔断方案进行自然通风的数值模拟。通过模拟结果的对比分析,得出了较优的隔断、进风和出风口方式方案,使室内绝大部分区域的空气龄低于5 min,为该建筑的自然通风设计提供了参考方案和技术支持。

Behavior of reinforced concrete structural walls with various opening locations: experiments and macro model

Two experimental tests of three-storied reinforced concrete structural walls having large openings were performed.Based on an original macro model,a multiple modified macro-model was proposed to develop a simple method to design a reinforced concrete structural wall with large openings and various opening locations.The interaction between reinforcement ties and concrete struts formed along the perimeter of openings was neglected in the original model.However,the strut-and-tie node was proposed to take account of such interaction in the proposed model.The predicted behavior of two specimens using such a proposed model was compared with the experimental results.It is shown that the behavior of structural walls with large openings could be modeled well using the proposed model.Moreover,the study indicates that the proposed model is applicable even in cases of multi-story structural walls having large openings and various opening locations.
