The composite material of concrete-filled steel tube (CFST) is modeled with the dual-unit method [6].
The compression strength and elastic modulus of the steel and the concrete are both introduced with the measurement data from material tests.

The absence of specific functional groups responsible for conducting protons in this polymer causes it to be used in conjunction with other materials that promote proton conductivity. 2-acrylamido-2-methylpropane sulfonic acid has good properties because of its water miscible sulfonic group, shielded amido group and unsaturated double-bond. sulfonic group endow it conductivity; amido group endow it good hydrolytic stability, acid-resistant, alkali-resistant and heat stability; active -C=C- endow it easy to generate copolymer with all kinds of vinyl monomers[5] The experiments in this study use AMPS as the primary proton donor because it allows reasonable proton conductivity in the PVA/PAMPS composite membrane.

Introduction Acoustic non-destructive methods of testing, in particular ultrasonic pulse method (UPM) and resonance method (RM) are used for determination of dynamic modulus of elasticity of materials – in particular concrete, and as a supportive method of evaluation of frost resistance of construction materials [5-7].
The advantage of non-destructive methods of testing is their rapidity and possibility of testing the same samples of materials with characteristics changing in time.

The design prospects of loading device (1) For the deterioration testing equipment of concrete materials under the action of multiple factor coupling, in order to simulate the actual situation of the project, load, steel corrosion, freeze-thaw cycles and other factors should be included in the scope of testing, and then reasonably determines the parameters of multivariate which are necessary to the equipment testing
(4) The development of testing equipment should integrate the characteristics of electronics, automation, machinery manufacturing, materials science and other disciplines, and gather related people together to design and manufacture better testing equipments.
