The use of sandwich structures in various engineering fields is growing rapidly because of advantageous features such as low weight and high strength-to-weight ratio.The existing theories are all based on soft core assumption.
Introduction Sandwich structures are widely used in marine, transport, civil construction and aerospace applications because of the significant feature such as its high strength-to-weight ratio.
Reissner theory, in spite of being simple in assumptions and equations, can satisfy the precision requirement of the general engineering construction[5].

Abstract.
As to reinforced concrete structure, the method to deal with the shortage of bearing capacity is one of the puzzles of structure engineering, so its reinforcement technology is a research hotspot.
At present, although there are many reinforcing methods of existing structures, FRP is the more widely used in engineering because of its efficiency, low cost, and beauty.
This project is financially supported by Graduate Cultivation Fund of Harbin Engineering University.
And this paper is funded by the International Exchange program of Harbin Engineering university for Innovation-oriented Talents cultivation References [1] National Standards of Peoples Republic of China.

As it’s known, historic roofings are load-bearing structures made of timber according to an empirical and intuitive design, without structural engineering theory support, and Banesa e Skendulate’s roof is a clear example of the “post and beam system”[1] and shows the ability of the local craftsmen to deal with the support of heavy stone roofing.
CHwB, organizes events, seminars, and restoration camp dedicated to young architects, engineers restorers and university students in order to involve them on the preservation of the Balkan Cultural Heritage which is not only the identity of these people, but also a treasure for humanity.
