In 2009 the center obtained a construction project “the civil engineering technology research center” in Guangdong Province.
Building structure fatigue performance testing experiment can help students to understand the phenomenon of fatigue in engineering structure, to understand the damage characteristics of different materials and the strength under repeated load is much lower than dead load, so it can enhances the students’ ability of designing complex structure.
At first, reinforcement mechanical properties (material mechanical experiment part) are tested in engineering laboratory, and then concrete mix proportion test of RC beam is carried out in material laboratory, at last structure experiment is to be carried out so it realizes the whole process between different laboratories.

Successive coating a lay of PSM on prestressed strand is a key to engineering application.
According to the engineering requirement the PSM can be modulated to solidify after 20, 30, or 40 d, and then the compressive strength comes up to above 30 MPa.
However, how to achieve successive coating a lay of PSM on prestressed strand is the key to the application of the postponed-set prestressed tendon to engineering.
It is convenient in engineering and it provides theoretical basis for conveying and extruding PSM in a single screw extruder.

Keywords: Applied damping material; viscoelastic material; topology optimization Abstract.Applied damping material (ADM) is today widely used to reduce vibrations and sound radiations by damping out the resonant peaks of structures.
Applied damping materials (ADMs) have been traditionally used to increase the system damping, for example, nowadays, it is very common for automakers to add passive constrained layer damping (PCLD) treatments to the structures like oil pans, front covers, valve covers, etc. to achieve low noise design.
implies no material in the element and implies the element fully consists of the materials. p is penalization factor of stiffness matrix.
Consequently, the objective smoothness of the optimization problem is enhanced to some extent, and the gradient filter method is seemingly efficient to prevent the checkerboards and the mesh-dependences in engineering applications.

As an example, the three points bending sample with two materials is investigated.
In the applying research of crack theory, how to make crack quickly is a key problem that meets demand of high efficient production in engineering.
