载荷密度 meaning in English

load density

After analyze the foundation of the current national code ( code for fire protection design of tall buildings gb500045 - 95 ) through experiments and fire simulations , the author has found that there are some limitations on the use of this national code for the designing of smoke management system in an atrium . this paper has been discovered that it is not enough when using the smoke layer interface height as a criterion to make an assessment on the safety rate in a building fire , or to calculate the egress time
通过上述实验研究和数值模拟研究，发现当采用我国现行的《高层民用建筑防火设计规范》（ gb50045 - 95 ）来指导中庭建筑的排烟系统设计时，在本文设计的火灾场景条件下（参照实际的中庭商场调研情况，即火灾载荷密度较大时），对于本文实验研究中所采用的相似模型及原型建筑，无论是采用自然排烟或者是采用机械排烟，其排烟量皆不足。
