INTRODUCTION The technique of Reverse Engineering offers methods for capturing information about physical models and transform into tri-dimensional data in a computer.
Today’s Reverse Engineering process basically includes two steps: 1) digitizing a physical part; 2) 3D modeling the part from the digitized data.
Producing an accurate 3D CAD model of a physical object has long been in the domain of reverse engineering contact acquisition devices.
This measurement technique, as well as other 3D scanning technology is used in many areas, such as surveying, civil and mechanical engineering, archaeology, historical artifacts documentation etc. [6].

Positive results in Brazilian research institutions have been developed on the use of NOCMAT (bamboo, vegetable fibers, bio-composites, recycled conventional materials, etc.) since 1979 at the Pontifical Catholic University of Rio de Janeiro (PUC-Rio, Department of Civil Engineering).
In countries such as China and India, bamboo is being used for thousands of years [3, 4] and currently for various purposes, including civil construction [5, 6, 7].
F) Civil construction [5, 27, 28, 29]: in housing, the technology developed enables cost reduction and time for building affordable housing [30, 31].
With the deepening of studies on the potential and advantages of using bamboo, eco plates materials or ecological wood, into the Brazilian civil construction and the increased use of methods for environmental conservation assessment, in a very few years, these NOCMAT will appear as fundamental ones to be specified in different civil construction projects by architects, engineers and managers interested to meet these methods and its criteria.

And the correlation equation of flexural capacity on the cross section of high-strength reinforced concrete beams strengthened with FRP is deduced according to different types of failure.The correlation equation is shown to be in good agreement with the experimental results, which can be referred to engineering application.
Introduction In recent years, high-strength concrete structure with high carrying capacity, reducing structural dead weight, increasing structure area, lower project cost, etc., adapt to modern structure to span, overload and towering trends, are being widely used in engineering practice,which are able to adapt to a modern structure to a large span, heavy and high-rise development trend[1]~[3].
However, the design and construction deficiencies in existing building , the transfer function of the building , and the impact of the environment and natural disasters, etc., caused some problems with the structure itself, resulting in performance degradation, which calls for high-strength concrete structure reinforcement and repair.And FRP (fiber reinforce polymer) with a corrosion-resistant, high strength, light weight, good durability are being increasingly applied to civil engineering structures [4].At present, the application and research about FRP focused on reinforced concrete structure strengthened with FRP in civil engineering, to be less for high-strength reinforced steel concrete structure strengthened with FRP.

Abstract.
The results obtained can provide theoretical basis for dealing with the stochastic problems in field of civil engineering and transportation.
Introduction In field of civil engineering and transportation, many real-life problems often require considering stochastic multiobjective programming (SMOP) problems[1], and the solution of such problems always be transformed into its equivalent deterministic multiobjective programming (MOP) problem initially, then solving the MOP problem, which is called multiobjective approach [2].
In most engineering applications, we want to minimize the random objective in the long run, therefore, the expected value is introduced to remove the random ambiguity in problem (1), and corresponding solution model can be presented as (2) Computing the set of optimal solutions of the deterministic problem (2) instead of the set of stochastically optimal solutions raises the question how the two sets of solutions are related to each other.
