Numerical Simulation For The Bearing Capacity Of Upper Structure Of The Damaged Framed High-Piled Wharf

At present,the framework of the high pile wharf large is widely used in water-head and multilayer mooring line of the port.Framework of the high pile wharf upper structure is higher,This structure-globosity is better and higher stiffness.Due to the framework of the high pile wharf have various type component,in addition to the damage caused by erosion,in its complex loading conditions,can also occur due to overload,fatigue,loss of different degree of degradation,the probability of damage can be larger.This will greatly influence on the performance of the wharf structure overall durability and bearing capacity,resulting in insufficiency of terminal security.Relying on a wharf design data in this chapter and the spot investigation,the stress of the wharf after an injury,reinforcement corrosion component bearing capacity after the change,and so on and so forth,the content is as follows:(1)Summarizes the high pile wharf wharf damage of all kinds of factors and conditions.Crime scene investigation of relying on the high pile wharf damage condition,the statistical analysis of the badly damaged parts are located mainly in the bottom of the panel and part of the beam,pillar node location.(2)According to rely on the design of the terminal data set up the project of lossless and lossy finite element analysis model,under various operating conditions on the structure stress calculation,analysis and comparison panel at the bottom of the bearing capacity of concrete spalling and cracks on the upper structure influence is limited,and the differential settlement caused by load of wharf structure is relatively weak in areas such as impact large longitudinal beam.(3)Based on the mechanism of corroded reinforced concrete member performance degradation,combined with the characteristics of the nonlinear finite element software,discusses the analysis method of corroded reinforced concrete members,and simulated by ANSYS calculation and analyzes the different corrosion degeneration on the mechanical properties of corroded components,it is concluded that corrosion rate of reduced capacity.
