Efficient calculation of daylight coefficients for rooms with dissimilar complex fenestration systems

The daylight coefficient (DC) method is a powerful and efficient method to perform annual daylight illuminance simulation. A set of coefficients are calculated for a given room space and static fenestration systems prior to simulation start. Time series of indoor daylight illuminances are obtained by only knowing the sky luminance. However, for rooms with dissimilar dynamic complex fenestration systems (such as windows with movable shadings) whose optical behaviour (transmission, reflection and scattering) may change during simulation, the efficiency of the DC method may be compromised as another whole set of coefficients must be re-calculated. This study presents the development of a new methodology to compute the DC set for rooms with dissimilar complex fenestration components only once prior to simulation start. A validation study is carried out, in which the daylight illuminances in an office space equipped with a clear window and internal Venetian blinds are compared using predictions from the present model, the Radiance program, as a benchmark model employing detailed optical model of Venetian blinds, and the Daysim program employing a simple engineering blinds model. Findings from the validation study show that the present model yields overall accurate results when compared with the benchmark model for any window orientation, although some local illuminance differences are observed in areas under direct sunlight exposure.     

城市商业与文化综合体节能分析

在经济与文化迅速发展的大时代背景下,城市商业与文化综合体顺势而生。这种＂商业搭台,文化唱戏＂的综合体模式不仅为文化艺术消费增添了新的刺激点,也为商业活动增添了更多魅力,具有巨大的优势。一时间,全国各大城市纷纷建设了许多城市地标性商业与文化综合体建筑。由于这种综合体结构复杂,功能区多种多样,其在采光、通风、采暖等方面能耗巨大,在为人们提供舒适的消费场所的同时,也因此消耗了大量能源。随着经济建设的深入,建筑能耗越来越高。因此,＂十二五＂规划以及＂十八大＂报告中都把＂大力发展低碳环保节能建筑＂作为发展低碳经济的重点。从规划设计角度,结合一些典型实例,从采光、通风与采暖等方面对商业与文化综合体的节能设计进行探讨与分析。     

Stresses and displacements in a circular ring loaded by symmetrically spaced radial forces

This paper presents the study of a plane elasticity problem for a concentric circular ring loaded by a system of equal radial forces equally spaced around its outer ring boundary. The problem is solved by the Kolosov–Muskhelishvili complex variables method. Explicit formulas are derived for calculating components of the stress tensor and of the displacement vector. Numerical values for circumferential stress and radial displacement are given for various ratios of inner and outer ring radii and various numbers of forces.

煤层底板突水风险智能灰靶模型的研究

分析煤层底板突水的灾变过程,以含水层富水程度、含水层平均水压、隐断层水文性质、隐断层发育系数、隔水层平均厚度和动底板岩层组合作为底板突水的风险辨识指标,通过效益型隶属梯度去除量纲干扰。应用灰色关联得到含水层因子、隐断层因子和隔水层因子,作为煤层底板突水风险的原始成分、必然成分和控制成分。提出煤层底板突水风险的智能灰靶模型,以效果测度向量区分安全、隐患和事故状态,实现了定性结果和定量赋值的有机融合。将模型应用到实践中,结果基本吻合实际,为研判复杂煤层底板突水风险提供一种新思路。

巷道复合顶板层间离层稳定性量化判据选择

为选择合理的巷道复合顶板层结间离层稳定性量化判据,选用巷道宽度、复合顶板岩性、复合顶板厚度及结构面黏聚力和内摩擦角5个不同因素,设计5×5共25组正交数值计算模型,采用ANSYS数值模拟软件分析不同地应力各数值计算模型中结构面应力和层间离层分布,并用工程实测进行验证.在此基础上,分析巷道复合顶板离层失稳力学机制.结果表明:巷道中心位置复合顶板层间离层值并不能敏感反映层间离层稳定性,采用巷道中部复合顶板结构面法向拉应力引起的局部分离范围作为离层稳定性判据更趋合理,其临界容许值和巷道宽度显著相关,一般为巷道宽度的0.50～0.75倍.
