| 3. | Test result suggests , in the serviceability limit states , displacement is littleer , the plane stiffness infinite assumption may be established
实验结果表明，在正常使用极限状态时，位移较小，同一楼层平面内刚度无限大的假定可以成立。 |
| 4. | This resonance usually exceeds serviceability limit state and ultimate limit state ; endanger hydropower station ' s economic operation , even safe operation
这种共振往往超出厂房结构的正常使用极限状态和承载能力极限状态，威胁水电站的经济运行乃至安全运行。 |
| 5. | Those include the load carrying capacity of the specimens in the limit state , the cracking load of the specimens , the crack width of the specimens and the deflection of the specimens
论文从四个方面进行研究：轻骨料混凝土板的正截面承载力，抗裂度，正常使用极限状态下的裂缝宽度和挠度计算。 |
| 6. | According to the empirica1 design methqds , we can safe1y say that the method proposed can satisfy the 1imit state of load bearing capacity as we11 as that of the serviceabi1ity l imit state
根据钢筋混凝土杆系结构设计经验，可以认为该法同时满足了结构承载力极限状态和正常使用极限状态的要求。 |
| 7. | Concentrating on the questions and developmental directions of engineering structure reliability , the applicability of building steel structures that is studied relatively less is analyzed and studied
围绕工程结构可靠性发展中的存在问题及其发展方向，对研究相对较少的建筑钢结构适用性（正常使用极限状态）方面进行了相应的分析和研究。 |
| 8. | Because the regulation of deformation limits in some kinds of codes is mainly provided by experiences , not calibrated according with the unified standard for reliability design of building structures ( gb50068 - 2001 )
鉴于适用性（正常使用极限状态）方面各规范对变形限值的规定还是以经验为主，而未根据《建筑结构可靠度设计统一标准》 （ gb50068 - 2001 ）的要求对其进行校准的实际情况。 |
| 9. | Secondly , according to the change of calculation formula when prestress were added to the chapter of concrete tower drum , the paper has given the calculation formulas of prestressed concrete tower drum in limited states of carrying capacity and normal serviceability
其次，针对高耸规范混凝土塔筒一章中增加预应力后，塔筒计算公式发生的变化，本文对预应力混凝土塔筒在承载能力极限状态和正常使用极限状态下的计算公式进行推导。 |
| 10. | So the concrete beams reinforced with frps not only increase the flexural strength but also increase the stiffness and decrease it ' s max deflection , which is very important to increase the ability of resisting reflex of the original beams and the strength of the normal use limit status
因此，纤维加固混凝土构件不仅提高了其抗弯承载力，而且提高了其刚度，减小了最大挠度，这对于增加原梁抵抗变形的能力、提高正常使用极限状态的承载能力具有十分重要的意义。 |
