分析了不同加固量、不同偏心距时碳纤维布的作用发挥程度；比较了在不同加固方式、不同加固量对破坏形态和加固效果的影响。

Many structural deficiencies and mistakes were highlighted, which including excessive horizontal displacement in the ground, more severe damaged transition layer (the first masonry structure layer), ground with farraginous structure, and poor construction quality. Finally, lateral stiffness ratio of the second to ground story in masonry buildings with RC frame structure at the bottom will be optimized following difference of materials between the ground floor and the upper floors. The strength and the ductility of transition layer, as well as shear walls in the ground floor, are crucial to keep the building standing during large earthquake.

在介绍和总结了汶川地震中底框砖房的表现―底层过大的水平侧移、过渡层严重破坏或完全坍塌、底层严重破坏或房屋完全倒塌、上部砌体整体发生侧移、以及设计一和施工质量良好的底层抗震墙砖房&大震不倒&的基础上，得出以下结论和建议：在抗震设防地区应禁止使用部分底框砖房，地震中过渡层的实际受力情况与设计所采用的受力状态有明显的区别，规范应考虑砌体和钢筋混凝土材料的不同力学性质来制定上下层刚度比要求，明确对过渡层的延性和强度要求，明确该类结构抗震概念设计的具体措施。

This effect is examined in this paper, and a reduction factor accounting for the effect of the complex stress state in U jacketed RC beams is proposed based on test results from literature.

该文研究了混凝土多轴应力状态对FRP-混凝土界面性能的影响，并根据试验研究结果，提出了U 形FRP 加固混凝土梁中FRP 剥离应变的折减系数。

Then, they were strengthened with RC jacketing and bonding steel plates respectively.

在第一阶段试验中，未加固的试件在低周反复荷载作用下使梁纵筋屈服。

The investigated test parameter of the specimens strengthened by RC jacketing were connection types between the new reinforced bars and the column.

屈服后的试件分别采用加大截面法和粘钢板加固，其中加大截面法加固的试件采用不同的锚固措施。

It can be precision milled into just about any shape or form providing the framework for the toughest of RC vehicles.

它可以精确碾磨成只是任何形式提供的框架最难的钢筋混凝土的车辆。

Large condensate gas pools are developed in the Ordovician and Carboniferous in the Lunnan low salient. Geochemical study shows that the Ro of gas condensate in these gas pools is in the range of 0.8% 1.0%(far below the threshold of R o＝1.3％ for thermal cracking), and the condensate gas is overmature dry gas (with R o＞2.0%). Moreover, the crude oil and dry gas in the study area were charged in different stages, indicating that the genesis of the condensate gas was not thermal cracking.

轮南低凸起奥陶系及石炭系发育大规模的凝析气藏，地球化学的研究结果表明，这些凝析气藏中凝析油 Rc 在0.8%~1.0％（远低于热裂解成因 R o＝1.3％的门限），凝析气为过成熟干气（回归 R o＞2.0％）；同时，区内原油与干气的充注期相异，表明轮南地区的凝析气藏并非热裂解成因的产物。

Through the investigation of three frame specimens with "π"pattern,this paper proves that the instable passibility of the frame column supporting wall would exist on condition that the design code requirements are satisfied, and presents a method used to analyze the elastoplastic stability.
