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。

Under the consideration of moneysaving and timesaving, a feasible way is to restrength damaged buildings instead of reconstruction. This research is based on a detail assessment process provided by the Ministry of the Interior. According to the basic requirement for structure design on strong column and weak beam, the restrength design will be studied.

本研究系以内政部建筑研究所所发表之「既有钢筋混凝土建筑物耐震能力评估手册」之详细评估法为基础，根据强柱弱梁之基本需求及梁柱不同之韧性表现，探讨耐震能力不足之现有建筑物补强设计之量化及选择补强位置之基本逻辑。

One flush end-plate external joint under monotonical loading and the other four joints under cyclic loading were tested. Failure modes and the effects of reinforcement ratio and concrete in column flange were synthetically considered during cyclic loading. Results of the experiments show that external flush end-plate composite joint also have quite hysteretic behaviors, better strength resistance and stiffness that are worth to promotion in seismic area.Based on experimental results and plastic analysis simplified formulas on moment resistance of semi-rigid composite joints were introduced.

本文对1个半刚性端板连接组合边节点进行了单调静力加载试验并对4个半刚性端板连接组合边节点进行了循环加载试验研究，主要探讨了节点的破坏模式以及混凝土板内纵向钢筋配筋率和柱翼缘内填充混凝土对节点性能的影响，试验结果表明端板连接组合边节点依然具有良好的滞回性能，较好的延性和耗能能力，是一种值得推广的半刚性梁-柱节点形式。

Nanning International Convention and Exhibition Center is a building of large-scale and complex structure system. Multiplicate types of structures and new technologies are applied in the project, including prestressed concrete, reinforced concrete, spatial truss, membrane and structural transfer floor etc.

摘要］南宁国际会展中心是一个规模宏大、结构体系复杂的大型建筑，在整个结构方案中，综合使用了多种结构形式和新技术，包括：预应力混凝土结构、钢筋混凝土结构、空间网壳结构、膜结构和结构转换层等。

Test results reveal that with the same area of the column section, the punching shear strength of the connections with nonrectangular columns is greater than that of the connections with square columns, and shear reinforcement can significantly enhance the strength and ductility of the connections with nonrectangular columns.

试验结果表明，与方柱－板柱连接试件相比，在柱截面积相同的情况下，异形柱－板柱连接试件具有较高的抗冲切承载力。抗冲切钢筋可以有效地提高板的冲切承载力和延性。

With the development of the marine in the world, more and more emphasis was paid to the structure of the outsea dolphin. According to the present economics condition of our country, the large-diameter reinforced concrete cylinder structure plugged into the base soil directly is a better style for the building of the deep-water dolphin.

随着世界上海运的发展，外海域墩式码头结构形式日益受到重视，采用钢筋混凝土大直径圆筒结构直接插入于地基土体的结构形式是我国目前经济条件下建造深水墩式码头的一种较好的结构型式。

The conclusion shows that the expansion joint may not be set in an overlength basement by setting the post-pouring strengthening band and temperature reinforced reasonably, adopting the shrinkage-compensating concrete along with doing a good job in temperature difference materials, production technology of concrete and construction.

通过合理设置后浇膨胀加强带和温度钢筋，采用补偿收缩混凝土及在环境温差、材料、混凝土生产技术和施工等角度做好控制，本超长地下室可不设置伸缩缝。

On the basis of summarizing the R-μ-T relation and overstrength effect in seismic design of RC structures, the different methods of "capacity design" measures in Chinese code and several influential foreign codes are compared, then problems existing in the seismic design of Chinese RC frame structures is put forward.

3在总结R-μ-T关系和结构超强效应研究成果的基础上，对比分析了我国建筑抗震设计规范及国外有影响的几本抗震规范&能力设计&的实施方案，提出了我国规范在对钢筋混凝土框架结构的抗震设计思路中存在的理论上的不合理之处。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
