The intention of this work is to establish theoretical basis for design of engineered concrete mixes whose characteristics would allow more efficient use of this material in severe environmental conditions.
The areas of civil engineering that will benefit from the outcomes most heavily are transportation and industrial structures.
Mix Design Two different concrete mix designs were used in the project: fibre reinforced concrete (FRC) used in load-bearing parts of bridges in the Czech Republic (C35/45 - XC4, XD1, XF2 - Cl 0,20 could be used as a good representative based on consultations with designers) and ultra-high performance concrete (UHPC) developed in the Department of Concrete and Masonry Structures, Faculty of Civil Engineering (FCE), Czech Technical University in Prague (CTU) in recent years by the team under supervision of prof.

Buckling Analysis of Double-Limb Lipped Channel Section Member under Axial Load Qing Ma 1, a, Jinsong Lei 1,2,b, Wenzhi Yin1,c 1College of Civil Engineering and Architecture, Southwest University of Science and Technology, Mianyang 621010,Sichuan, China; 2College of Civil Engineering, Hunan University, Changsha 410082, Hunan, China amaqing1028@hotmail.com, bleijinsong2003@163.com, clzqfzhw@sina.com Key words: Double-Limb Lipped Channel Section; Geometrical Parameters; Buckling Performance; Ultimate Bearing Capacity Abstract: Double-limb lipped channel section steel member is formed by connecting two single limb members with bolts in order to improve the buckling performance.
Therefore, the geometric dimension of section should be controlled effectively basing on meeting the engineering requirements, (3) For the member with smaller wall thickness, considering the keyholes have little effect on buckling performance of double-limb lipped channel section, so they were not taken into account when buckling analysis, but in practical application, the strengthen of web with more bolts should be checked according to net sectional area in order to prevent the web destroying due to local stress concentration

Finally, some optimization plans and appropriate protective measures are suggested, providing a theoretical basis for engineering practice.
To select the proper approach, we must have profound understanding of engineering background as well as the method itself.
SLOPE/W has become the widely used professional analysis software in the field of geotechnical engineering for slope stability analysis.
It includes a variety of methods (Morgenstern-Price, GLE, Spencer, Bishop, Ordinary, Janbu, Sarma, Corps of Engineering, Lowe-Karafiath) for geotechnical engineering problems such as the shape change of slip surface, pressure condition of pore water, soil property as well as different loading ways.
Thus, the SLOPE/W software can deal with almost all the problems of slope encountered in the geological structure, civil engineering, mining engineering.
