钢筋

"This reconstruction has meant the loss of wonderful old houses and some wonderful architecture, and its replacement with fake things of tile-covered steel and concrete," says Zhang Wei, a resident and conservationist.

张伟是前门地区的一位居民，也是一名主张保护传统的人士。他说：&这一改造工程，意味着我们失去了许多出色的旧住宅和一些精美的老建筑。取而代之的，将是一些砖瓦覆盖的水泥钢筋制成的仿制品。&

It has unique architectural configuration,complex functions and big construction difficulties.A lot of technologies were applied to the construction to meet the design requirement and guarantee construction quality,such as tie plate or connector between profile-steel concrete column and steel beam,melted groove welding for steel bar ...

施工中采用包括型钢混凝土施工技术、型钢柱与混凝土梁采用连接板及连接器的应用技术、钢筋熔槽焊连接应用技术、自密实混凝土应用技术、录音棚房中房模板设计、弧形看台与斜柱施工技术、舞台桁架高空散拼施工技术、大型屋面钢网架安装技术、桁架整体提升技术、复杂形体幕墙安装技术、8坐标系统测量控制技术等，满足了设计要求，保证了施工质量。

The pass system and guide design key points were introduced of applying three-strand splitting rolling technology for Φ10mm ribbed bar on semi-continuous small section steel rolling line.

介绍了在集中传动的小型半连轧线上生产Φ10mm带肋钢筋采用三切分轧制工艺的孔型系统、导卫设计要点及生产中应注意的问题，现已连续生产6万余吨，成材率达101。

A 1/7-scale model of three-bay, three-span frame-bent R.C. structure is the first and the largest size in the same testing field in China by now.

选取3跨3榀钢筋混凝土框排架子空间模型进行拟动力试验，这是国内首次对该类型结构体系进行的大型动力试验。

As one of the important steel material products in modern industry, the thread steel bar is used for the architecture primarily.

螺纹钢筋是现代工业中的重要钢材产品之一，主要用于建筑行业。

Because the height of box girder is limited, vertical prestressed bar is short, so when control stress of prestressing is attained, elongation of thick high strength thread reinforcing bar is limited.

这是由于箱梁的高度有限，竖向预应力筋的长度都比较短，因而在达到张拉控制应力时高强精轧螺纹粗钢筋的伸长量有限。

Designing with this CARD system can shorten the design cycle of the new product, lowering the consumptions of the mills and the production cost, advancing the dimensional accuracy and the mechanical character of the finished thread steel bar. It has the important significance for increasing the economic benefit of the enterprise.

采用本螺纹钢CARD系统进行孔型设计，极大地缩短了新产品的设计周期，降低了轧机能耗和生产成本，提高了螺纹钢筋成品的尺寸精度和机械性能，对增加企业经济效益具有重要意义。

Chapter 3 presents the shaking table test of the reinforced concrete frame model, it includes test model, test load modes and treatment of test data, which provide the basis of the building model.

第三章 介绍了钢筋混凝土框架结构模型振动台试验，包括试验模型，试验工况，试验数据的处理，为所建模型提供了试验依据。

For a doubly reinforced beam, reinforcement area in both the tension and compression zone are calculated

双筋梁在截面受拉区和受压区同时按计算配置受力钢筋。

A crack in the tension zone of the concrete implies that some slip has occurred between the steel reinforcement and the surrounding concrete.

在混凝土受拉区出现裂缝意味着钢筋与周围的混凝土之间产生了一些滑移。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
