摘要
通过对宁夏大学教学楼内不同功能教室活荷载的调查与统计分析,建立了不同功能教室的准永久荷载及临时性活荷载概率模型,得到教室的活荷载标准值为1.5kN/m2.经过数理统计中x2检验和K-S检验,活荷载均服从极值I型分布.将调查统计的活荷载标准值与2012荷载规范进行比较分析,发现现行荷载规范中教学楼活荷载标准值取2.5kN/m2是安全可靠的,但安全储备过大.从节省能源考虑,建议采用2.0kN/m2作为活荷载标准值进行结构设计.
Through the investigation and statistical analysis of live loads of teaching building floors in Ningxia University,we established the probability model of quasi-permanent and temporary loads of class- rooms of different functions,obtained the live load standard value of classrooms（1.5 kN/m2）. Through the x2 text and the K-S statistical test in mathematical statistics,the live loads were discovered to be subject to the extreme I distribution. Comparing the investigated live load standard value with the 2012 load code,we found the live load standard value of 2.5 kN/m2 was safe and reliable according to the existing load code, but the safety reserve was too large. For saving energy,the live load standard value of 2.0 kN/m2 is recom- mended as suitable and feasible.
