This fatal injury greatly affected normal operation and durability of curved beam structure [2].
Engineers hope to improve the mechanical properties by effective means, in order to enhance the durability and prolong the service life of curved girder.
Through study of natural frequency of external prestressing curved beam(controlled by factors of curved girder span, section properties etc.)
There are many factors affecting external prestressing curved beam’s dynamic performance.
Before doing dynamic test, mechanical properties of test material must be determined, such as concrete strength, ultimate strength, tensile strength of strand, and yield strength of non-prestressing reinforcement.

The calculation with submodeling is based on the logic of changing the reference frame from a primary model (global model) with a well-defined coordinate system and mechanical properties.
Recently, the influence of bone cement handling procedures on their functional properties was studied in vitro by Rubo et al. [13].
They found that the friction coefficient along the contact surfaces of specimen with indenter has no pronounced effect on the measurement of mechanical properties of bone cements.

This article discusses the surface modification effect’s laws in a high-voltage electric field on the autogenous properties of mineral dispersed concrete components, structure formation processes, mechanical properties, and cement stone hydration products.
The properties of concrete largely depend on the content of fine fractions in cement, which also determines the packing density of particles [5].
The aim of this work is to establish the laws of the surface modification effect on the autohesion properties of mineral dispersed concrete components, the process of structure formation, physical and mechanical properties and the cement stone hydration products.
The change in the electro-surface properties of the powders should also affect the interparticle interactions in the solid-liquid system.

Simulation of road surface roughness Road surface condition is a very important factor that affects the dynamic responses of both the bridge and vehicles.
Because the bridge responses due to moving vehicle loads are affected by many factors, the effects of road roughness, vehicle velocity and bridge damping on bridge responses are analyzed in present study.
When the bridge damping increases, the typical responses of bridge and their dynamic amplification factors decrease.
However, the dynamic amplification factors of typical responses of bridge decrease without large amounts.

The kinds and characters of waterborne polyester is a key factor to decide the characters of WBPU.
Adding nano-sized materials into the system could endow the WBPU film better mechanical strength and other properties such as resistance to ultraviolet ray, heat insulation due to its small size effect.

Adopting Coulomb friction model in the study on sliding friction, Kebadze and Kraincanic[5] studied the nonlinear bending properties of marine flexible risers.
Then the effects of key structural parameters on local structure properties of pipes were alse studied.
The most critical structural parameters affecting the compression stiffness are the tensile stiffness and helix angle of the spiral steel belt in hoop strength layer.
Six parameters affecting the bending stiffness are studied here, including (tensile stiffness), friction factor, helix angle in the tensile strength layer, and (tensile stiffness), (bending stiffness), helix angle in the hoop strength layer.
The former determines the bending stiffness before sliding of the tensile strength layer while the latter two factors may delay the sliding phenomenon of the tensile strength layer, therefore strengthening the overall bending stiffness of the pipe. 2) The bending stiffness is also greatly influenced by the helix angle, the friction factor between separate layers, and the bending stiffness of the steel belt (EIr).
