To increase of blast resilience of whole structure, a complex static assessment have to be done with tha analysis of the structural system of building, dimensions and mechanical properties of the load bearing elements materials.
These can be obtained experimentally or using sample assessment if possible (not all materials could be destructively or semi destructively sampled to obtain their precise characteristics).
The suitable retrofit technique has to be used in regard to the historic materials involved, degree of their decay and preservation of their unique authenticity.

Abstract.
To optimize system performance and minimize energy loss, various pipe diameters, flow rates and pipe materials were examined.
Calculating the head losses and friction factors in inter-basin pipe network The materials and the wall-roughness of the two pipes are different, which results in different friction, as shown in Fig. 6.

Whether titanium alloy material can be well used in offshore oil and gas pipelines have been evaluated, this study will be a supplement of the research on titanium alloy oil well pipe materials.
The results showed that both titanium alloy materials had better corrosion resistance.
The tests were conducted by referring to GB/T 15748-2013 "Marine Metallic Materials Galvanic Corrosion Test Method" for testing.
It can be concluded that TC27 titanium alloy materials have excellent corrosion resistance and better comprehensive performance, which can effectively meet the needs of high-strength and corrosion-resistant downhole tubing materials.

The results showed that the correlation effect of dual defects produce more severe stress concentration phenomenon on the associated region of ferromagnetic specimen, and had no obvious effect on the edge of ferromagnetic materials; Gradient value K of the normal component H(z) of leakage magnetic field in the specimen, as a parameter evaluation of stress concentration in the specimen, has high reliability in areas without correlation effect, but it has no credibility in areas under dual defect correlation effect.
When dividing grid unit, method of manual control unit size and freedom divide is adopted, making the grid of ferromagnetic material area and the air layer area near prefabricated defects relatively dense and grid away from the prefabricated defects relatively sparse [8-9].

Abstract.
Although independent management has been realized, it cost massive manpower and material resources.
The raw materials of concrete are so many; including cement, fly ash, water, carpolite, grit, additive, etc., the ratio of these materials will affect the compressive strength, flexural strength of concrete.
Action and Agency in Cognitive Science.

Abstract.
In order to evaluate different gettering strategies for SOI wafers by using computer modeling, one has to know with sufficient accuracy the diffusivity and segregation coefficient of transition metals in SiO2, as well as material parameters required to describe the gettering techniques typically used in combination with SOI, such as polybackside gettering and internal gettering.
