The flexural stiffness as well as the maximum moments and their failure positions of the tube [90/±45/0] with different thickness of every layer are derived for the application and design in engineering.
The tube consisting of cylindrically orthotropic layers, particularly with inner layers of , is significant in engineering because their fibers can contribute to the stability around the circumference.
Such results are useful for the application and design of composite tube in engineering.
For the application and design in engineering, the flexural stiffness as well as the maximum moments and their failure positions were derived as the function of the percentages of layer thickness.

In order to realize the recycle of waste tires, rubber concrete can be utilized in road engineering.
Introduction In road engineering, the ordinary concrete pavement is easy to cause cracks under vehicle load during a long time, which leads to insufficient durability and shorter service life.
With the purpose of improving the durability and economic efficiency of the this concrete in road engineering, the ratio of rubber should be less than 20%（3）随着橡胶掺量的增多，试块剪切强度均下降，但而且当橡胶掺量大于20%后下降更明显，道路工程中为了提高耐久性，同时考虑经济性，应选用橡胶掺量小于20%的混凝土配合比。

One important reason is that engineering accident caused by groundwater is constantly emerging.
According to statistics, engineering accidents caused by groundwater account for 21.4% [3].
In the practical engineering, pore-water pressure measured is not always equal to static water pressure [9,10].

Experiment Study of Optimal Combination of Strength for Mortar and Block of Autoclaved Sand-lime Brick Masonry Zhongji Zhang School of Civil Engineering and Architecture, Changsha University of Science and Technology, Hunan Changsha, 410004 China zzj191001@sohu.com Keywords：Experiment study; material character; autoclaved sand-lime brick; optimal combination of strength for mortar and block Abstract In order to write Hunan province engineering construction local standard named" Technical specification for autoclaved sand-lime brick masonry building ",the author has finished a series of fundamental mechanical properties experiments on autoclaved sand-lime brick masonry such as material character experiment, shear strength experiment , bending tensile strength experiment.
The study of literature [5] shows that: because the vertical mortar is not full in practical engineering and the vertical mortar shrink, they greatly weaken even completely destroy rapping between the vertical mortar and brick.
