文章以本科旅馆建筑设计方案为研究对象,利用采光模拟软件PKPM-Daylight,模拟全阴天工况下该建筑客房的室内采光效果,并通过调整客房的进深、侧窗面积再进行对比分析。模拟结果表明建筑在方案设计中若采用8.1m的进深,将对客房采光产生不利影响,学生在建筑方案设计时应当注重采光等建筑技术方面对于建筑空间的影响。 相似文献

我国青少年近视率大幅增长,引起社会广泛关注,室内光环境差是近视高发的重要因素之一。通过Ecotect和Radiance软件模拟,对陕西延安地区中小学校的教室窗户进行定量设计研究。当教室宜采用高度适中,窗间墙宽度适中、布置均匀的窗户时室内照度和采光系数较好。为减少教室内眩光,可在窗户上增加1000mm(内)+500mm(外)的遮阳反光板。增大教室内墙窗户可有效提高教室内照度和采光均匀度。窗户是中小学教室自然光线的唯一来源,因此窗户形式的设计对改善室内光环境有重要意义。 相似文献

For a typical lone high-rise 20-storey residential building in Hong Kong, the extent to which cooling of its 10th-floor (mid-level) rooms depends on overhangs and side fins was evaluated. By using the software EnergyPlus?, it was found that the application of overhangs would reduce the electricity consumption by up to 5.3%. The highest reduction was obtained in rooms with windows unshaded by own-wing walls, face west, and have 0.75 m overhangs. By using the same software, it was found that the application of side fins to the building with overhangs would reduce the electricity consumption by up to 1.4%, where the highest values belong to windows facing either north or south (at west wing), with out-of-core side fins. 相似文献

Steel–concrete composite shear walls using precast high performance fiber reinforced concrete panels
In this research, seismic performance of composite steel plate shear walls (CSPSWs) using high performance fiber reinforced concrete (HPFRC) panels is experimentally and numerically investigated. Three one‐story one‐bay CSPSW specimens using precast HPFRC panels were designed and fabricated for cyclic quasi‐static experiments. The HPFRC panels of composite shear wall specimens did not have any steel rebars. The main purpose of the study was to understand the effects of rigid and semirigid HPFRC panels on the seismic behavior of the system. Shear capacity, ultimate shear strength, lateral stiffness, energy dissipation, and ductility ratios of the specimens are evaluated. The experimental results demonstrate that specimens were able to resist lateral load up to at least interstory drift of 6%. Using HPFRC panels, CSPSW specimens becomes stiffer in the elastic region, and the yield displacement of the shear wall is decreased; therefore, the ductility ratio of the system is increased. It should be noted that ultimate shear strength, initial elastic stiffness, and energy absorption of specimens with an HPFRC panel on one side or both sides of the infill steel plate were approximately the same. However, using two HPFRC panels is not economical in comparison with CSPSW with an HPFRC panel on one side. Additionally, the second panel increases the seismic mass of the structure. 相似文献

This paper presents axial compression tests on longitudinally stiffened aluminium panels in alloy AA6082 temper T6. A specially designed test facility is presented. The panels are built up with extruded aluminium profiles connected by longitudinal welds. Two panel types are considered, with open section (L-shaped) stiffeners and closed section stiffeners, respectively. The experimental programme comprises tests on single panels supported along all four edges and as a special case panels supported at two edges only. Tests on panels with lengths 1.0 m and 2.0 m are reported. Two deformation modes were observed in the tests; regular flexural buckling of the entire panel towards either the stiffener side or the plating side, and, for the case of the panels with L-shaped stiffeners, collapse initiated by stiffener tripping. The panel resistance is compared with the design resistance obtained from the European standard for aluminium structures, Eurocode 9. For all panels the experimental capacity exceeded the design value. 相似文献
