Steel and concrete are the main buiding material of the civil engineering community, but with its easily errosion behaviour and CO2 discharge, it should be substituded with new materials.Fiber reiforcement polymer (FRP) is such a developped material, with its high strength to weight ratio, durability prolongation, hight stiffness to weight ratio and its fatigue resistance behaviour, it is now getting widely used in civil engineering.
In June 2011, China Transportation Ministry developped its engineering durability standard and encourage the Chinese civil engineers to use new non-steel materials into the construction industry [2].

Abstract For measuring in-depth residual stress in 3D cylinder structure easily in this paper,
the semi-destructive incremental hole drilling technique combined with finite element method is
used, the calibration coefficients of 3D cylinder components are calculated, and the relationship
between strain and stress is determined, the changes of calibration coefficients are analysed, the
residual stress of one steering joint of automobile is measured, and the errors of residual stress are
discussed.
The results of calculating by calibration coefficients of cylinder and CETIM engineering measurement are shown in Fig.4. 0,0 0,5 1,0 1,5 2,0 2,5 3,0 3,5 4,0 0 60 120 180 240 300 360 420 480 540 Residual Strain Drilling hole depth H/mm ε1 ε2 ε3 (a) Strain 4 0,0 0,4 0,8 1,2 1,6 2,0 2,4 2,8 -800 -700 -600 -500 -400 -300 -200 -100 0 Residual Stress σ/MPa Drilling hole depth H/mm σx-cylinder σx-plane σy-cylinder σy-plane (b) Residual stress Fig.4 The calculation result of cylinder model When the cylinder model is used to calculate the residual of cylinder component structure, the residual stress value is bigger than the result of plane model by CETIM.

Moreover, advanced tools appear to be geared toward consultants and specialists (expert users) rather than primary building designers.
Needless to say, recent years were characterized by high cost and time pressure in the AEC sector (Architecture – Engineering – Construction), a fact that adds even more complexity to the mentioned aspects.
Therefore, architects are increasingly seeking inspirations and adapting innovations from other fields such as engineering, advanced computing, and building science.
Can users count on online support or user forums to solve their issues?

Abstract: Magnesium (Mg) alloys are becoming one of the key engineering materials for aerospace
and automotive industries because of their low density, high specific strength, excellent
machinability and good diecastability, etc.
The Changchun Institute of Applied Chemistry (CIAC) developed an electrolytic advanced process for producing the binary Mg-RE alloys such as Mg-Y, Mg-Nd, Mg-Ho, Mg-Gd and Mg-LPC (La, Pr, Ce) with homogeneous structures and good performances.
