1) drill-string in compression
钻杆受压
2) compressive chord member
受压弦杆
1.
In some truss structures,such as the roof truss undergoing heavy upward wind load,or the truss on both sides of a footbridge connecting different buildings,the service conditions do not allow us to place lateral support for the compressive chord members.
在一些受较大向上风载的屋架或连接不同单体建筑步行桥的两侧桁架等结构中,由于受到使用条件限制而无法为受压弦杆设置平面外的支撑系统,因此这些结构中受压弦杆在平面外的稳定问题就显得格外突出。
2.
The calculation for the effective length of the compress ive chord members in the truss can not be considered as hinged joints or fixed i n each member end,because the compressive chord members of the truss are restra ined by the contiguous ones.
桁架受压弦杆受到相邻杆件的约束,其计算长度不能直接按两端铰接或两端固定杆件来取值。
3) compression member
受压杆件
1.
Basing on the comparison of the limitations Of compression member slenderness ratio, flange width- thick-ness ratio, web depth-thickness ratio, the author analyses the differences and similarities Of the Chinese and the American steel structure design codes and regulations.
通过比较现行中、美两国的钢结构设计规范、规程中对受压杆件的长细比、翼缘宽厚比、腹板高厚比的极限值规定，阐述两国规范、规程中的差异和近似之处。
2.
By comparing local stability limits of I-shaped compression member web for steel truss in both seismic and without seismic areas,main influence factors of local stability of I-shaped compression member web in steel truss are proposed,as well as the solving methods.
通过钢桁架工字形截面受压杆件腹板在抗震设防区与非抗震设防区局部稳定限值的比较,提出了影响钢桁架工字形截面受压杆件腹板局部稳定的主要因素和解决方法。
4) compression diagonal
受压斜杆
5) inner pressure inside pipe
钻杆内压力
6) Euler's pole
受压细长杆
1.
A geometrical relation between longitudinal displacement and transverse displacement of a Euler's pole is(obtained) by Lagrange's description method,and a nonlinear dynamic model expressed by partial-differential equations is(established.
利用Lagrange描述法建立了受压细长杆因弯曲引起的轴向位移与横向位移之间的关系,并建立了由偏微分方程组描述的非线性动力学模型。
