| 中文摘要: |
| 针对利用屋顶铺设光伏太阳能板的光伏发电项目中，光伏太阳能板对屋顶风荷载的影响问题，采用刚性模型测压试验，得到安装光伏太阳能板屋顶的风压和未安装光伏太阳能板屋顶的风压。分别计算两种情况下屋顶风压系数均值、风压系数正向极值、风压系数负向极值以及屋顶局部体型系数。结果表明，安装光伏太阳能板对屋顶整体风荷载的影响不大，但增大了局部的最强风吸力;安装在屋顶的太阳能光伏板体型系数随位置变化不敏感，取值均在正负0.2之间。 |
| 英文摘要: |
| Solar panels, used to photovoltaic generation, influence the wind load on the roof equipped with panels. Employing the rigid model pressure test technique in wind tunnel, the comparison of wind pressures on roof at cases of with panels equipment and without panels were conducted. The mean value of wind pressure coefficients, the positive extreme of wind pressure coefficients, the negative extreme of wind pressure coefficients and the local shape coefficients were used to evaluate the influence of solar panels on wind pressure. The result shows that the effect of solar panel on total wind force is negligible, but the local suction wind load increases in case of panels equipment; wind pressure on solar panels is not sensitive to location, with the value of shape coefficients on panels between -0.2 and 0.2. |
