negative moment meaning in Chinese
负地形
负矩
负力矩
负弯矩
Examples
- However , the cantilever beam ’ s concrete deck of this structure will be cracked easily at the negative moment region
该结构悬臂挑梁根部混凝土板承受负弯矩,容易开裂。 - Fail modes which are influenced by prestressing levels , length of negative moment reinforcement and fire case are proposed
考察了预应力度、负筋长度及不同受火工况对破坏形式的影响。 - However , the stud welding roots in the negative moment region of the beam are often subjected to the joint action of shear stress cycling of the studs and tensile stress cycling of steel girder flanges
但在负弯矩处栓钉焊趾往往承受栓钉剪应力循环和钢梁翼缘拉应力循环的共同作用。 - From the test results , suggestion that negative moment reinforcement should run through the specimens to postpone the crack ' s appearance and improve the specimens " fire endurance are also proposed
由此提出了拉通板顶负筋的建议，以延缓横向贯通裂缝的出现，达到保护预应力筋和提高连续板耐火性能的目的。 - Therefore , the scientific scholarsboth at home and abroad have been carried series of research work since the 1960s , with some defects still remaining unresolved . the objects of this research are : ( 1 ) to analyze the course of the crack , itsappearing and development , and discuss the major factors influencing the behavior ofthe negative moment region in continuous composite beam . ( 2 ) to establish the modeand formulas of the crack width by the theoretical analysis
本文研究的主要目的是通过对组合梁负弯矩区裂缝的出现、发展的过程分析,讨论影响钢-混凝土连续组合梁负弯矩区受力性能的主要因素,建立了组合梁负弯矩区裂缝计算模式和裂缝宽度的计算公式,并初步探讨了连续组合梁合理截面形式。
