Secondly , the reinterced concroto t ? shaped benm shuld be strong thened . the t - shaped benm of the or glanl superst theture was implomentod neeording to the standnrd design issued by the ministry of communications in 1964 二是钢筋砼t梁加固，原上部结构t梁按1964年交通部颁布的标准图实施，能否满足汽? 20级、挂? 100的要求。
The main problem won1d be whether tenslle stregth conld sallsfy the demand of truck - 20 and trailer - 100 . after calculating internal forces . it is confirmed that the t - shaped beams with 16 . 8m per span can meet the demand , while the ones with 22 通过内力计算，跨径16 . 8mt梁能够满足新的荷载条件下的各项标准，跨径22 . 2mt梁采用更换预应力钢筋砼t梁方式解决。
The complete deformation process of a t - shaped column is then analyzed . the load - carrying and deformation behaviors and the main factors affecting these behaviors of such a column are studied in detail 在此基础上，对一t形截面长柱的全过程进行了更为详尽的模拟计算，得到了组合长柱在偏心荷载作用下的受力和变形规律，并对影响这些规律的主要因素作了分析。
3 analysis on axial compression ratio of l , t and + - shaped columns is undertaken . it indicates that for l and t - shaped columns , axial compression ration is very low when web is in compression , but for + - shaped columns , axial compression ratio approaches to that of rectangular columns 3对l 、 t 、十形柱轴压比限值进行计算分析，指出l 、 t形柱当腹板受压时轴压比限值很低，十形柱轴压比限值同矩形柱相差不多。
Meanwhile the effects of slenderness ratio and load eccentricity on the ultimate load - capacity of slender composite columns are numerically analyzed and discussed in detail . then a t - shaped slender composite column under axial load and two groups of slender composite columns of rectangular cross section subjected to combined biaxial and lateral loads are analyzed , the load - carrying and deformation behaviors of such columns are analyzed and discussed 在此基础上，对一偏压荷载作用下的t型截面组合长柱和两组横向与偏压荷载共同作用下的矩形截面长柱分别进行了实例计算，就不同荷载情况下组合长柱的受力与变形特性进行了分析和讨论。
2 the effects of load angle on load - bearing capacity of l , t and + - shaped columns under axial compression and biaxial bending are discussed . as for l and t - shaped columns , load angle has a great effect on bending capacity of them , mainly because of the asymmetry of sections . but for + - shaped columns , the effect of load angle on load - baring capacity is not much significant 2讨论了荷载角对l 、 t和十形柱受弯承载力的影响，表明l 、 t形柱由于截面不对称，纵筋分布不对称，造成某一荷载角下承载力较大，而另一荷载角下承载力又很低。
There was interesting one that " came straight to the point " , nearby " association of jiangxi " of ancient building with a history of more than 200 years , horizontal street of the west nearby is connected to west street , form , have " t - shaped road junction " and light square , bank , internet cafe , market , restaurant , bookstore , gallery of characteristic , etc . spread all over it most , prove to be the good place for travelling , lying fallow , shopping 并有”开门见山“之趣，附近有200多年历史的古建筑”江西会馆” ,旁边的西横街与西街相接,形成最具有特色的”丁字街”和小广场银行网吧商场餐厅书店画廊等遍布其中，不愧是旅游休闲购物的好地方。
In static test , t - shaped and l - shaped specimens were respectively divided into four groups according to concrete strength grades , sectional height to thickness ratio , reinforcement ratio and ratio of axial compressive force to axial compressive ultimate capacity of section . how these factors affect the load - carrying and deformation of short - leg shear wall is known by analysis the result 在拟静力试验中对t形和l形短肢剪力墙分别进行了四组试验，通过对试验结果的分析，揭示了混凝土等级、截面配筋率、轴压比和墙肢截面高厚比等因素对短肢剪力墙承载力和变形的影响。
This paper deals with the water - bearing media and water - bearing quality of the rocks in the damsite , at first , then it concludes two water - bearing space structures , namely , t - shaped and y - shaped structures , after the classification of the different rocks ' water permeability . furthermore . on the basis of the dynamic state of the ground - water and the hydrogeological conditions of this area , the groun - water system of the area has been prelimilarily divided accordingly 本文首先研究了坝址区出露岩体的含水介质和含水性，并对岩体透水性进行了分类，总结出了两种岩体的含水空间结构，即“ t ”字型与“ y ”字型结构。在此基础上通过研究地下水的动态，以及水文地质条件对本区的地下水系初步进行了划分。
To investigate the punching shear behavior of slab - column connections with nonrectangular columns , an experiment on the three specimens of column with three kinds of typical special - shaped cross - section ( cross - shaped section , t - shaped section and l - shaped section ) , which were connected with reinforced concrete slabs , and reference specimens with square columns was conducted 摘要为了研究柱截面形式为异形柱的板柱连接冲切受力性能，进行了柱截面形状分别为3种典型异形柱（十字形、 t形和l形）和对比方柱所构成的板柱连接的冲切特性试验。
