1引言土木工程早期的技术成果中大部分力学计算公式都是根据经验得来的,工程中脚手架的设计计算也是同样,缺乏可靠的理论支撑。受当时社会生产力发展水平的限制,无可信的实验数据借鉴,仅仅是凭工程师的经验来设计。到了现代,在理论依据不健全的情况下,金属脚手架的大范围普及主要得益于生产力的发展水平的提高,有条件进行大规模的科学实验。这些大量的实验有些是科研院所,但大部分都是脚手架生产企业所
1 Introduction Most of the early civil engineering results of mechanical calculation are based on experience, engineering design scaffolding is the same, the lack of reliable theoretical support. Limited by the level of development of social productive forces at that time, there was no credible experimental data to draw lessons from, just designing with the experience of engineers. In the modern era, due to imperfect theoretical basis, the widespread popularization of metal scaffolding has benefited mainly from the improvement of the level of development of productive forces and the conditions for conducting large-scale scientific experiments. Some of these large numbers of experiments are scientific research institutes, but most are scaffolding manufacturers
