drift limit meaning in English
流速限定
Examples
- Being with great flexibility , however , it is not economical to meet the inter story drift limit when the building is high
但由于其柔性较大，楼层较多时满足侧移要求不够经济。 - And before second - order drift limits have been established , the equations about second - order drift calculation which can be used in practice are required to be set down first
在确立二阶侧移限值之前,则需要先明确能应用于工程实践的二阶侧移计算公式。 - First - order lateral displacement analysis and second - order later displacement analysis are different approaches for drift analysis , and they need different drift limits to be adapted
一阶侧移分析与二阶侧移分析是两种不同的侧移分析方法,需要不同的侧移限值来与之相适应。 - Based on these principles and equations , this paper attempts to give a prepositional equation for simplified analysis for second - order drift . through the elementary research on second - order drift limits , this paper gives a second - order drift limit to one - bay - one - story steel frames , a second - order total building drift limit and a inter - story drift limit to multi - stories steel frames
本文在这些理论的基础上,系统考虑了竖向荷载对侧移影响、假想荷载对侧移的影响和侧移计算时的荷载组合等问题,尝试性地提出了二阶侧移简化计算的建议公式。 - Code for design of steel structure gb50017 - 2003 , the being employed code in china , has codified the basic theory about second - order analysis , but there is no criteria about second - order drift , and the drift limits in the code can be only used in first - order lateral displacements analysis . therefore , it is urgently that researches are needed on second - order drift analysis and on how to establish the new limits for second - order drift . it ’ s a practical problem that researching how to establish second - order drift limits , and some conditions relative practical engineering are required to be taken into account
我国现行规范《钢结构设计规范》 ( gb50017 - 2003 )已经将二阶分析的原理列入其中,但规范中尚未涉及二阶侧移计算的有关内容,规范中规定的侧移限值也仅限于对一阶侧移的约束,这就迫切需要对二阶侧移计算方法进行研究,以及确立考虑二阶效应后钢框架结构的侧移限值。
