Evolutionary Structural Topology Optimization for Cantilever Construction of Continuous Rigid-Frame Bridge Wenhui Zhang1, a, Yaoting Zhang1, b and Guoqing Li1, c 1School of Civil Engineering and Mechanics, Huazhong University of Science & Technology, China asobyebye11@163.com, bzyt1965@mail.hust.edu.cn, clig57@mail.hust.edu.cn Keywords: topology optimization, continuous rigid-frame bridge, engineering constraints, the filter scheme.
The Ishai stress criterion [5] is more applicable to the optimization of concrete structures than von Mises stress criterion, because the Ishai stress can describe the features of different type materials, and the concrete materials have the property with different features in tension and compression.
The elasticity modulus of all artifical material elements is set to , where E = the elasticity modulus of the real material; and rw= the ratio of the weight of the elements with birth capability in the current design domain to that of the initial design domain with a fixed finite element mesh fully filled with material.

The horizontal component paralleled to the surface of materials plays a dominant role when the incident angle of liquid is 30°, the morphology of scoured surface of materials is presented wavy folds, and there are more short-cutting marks at the same time.
The solid particles with high speed cut the surface of sample continuously, which made the materials loss constantly (Fig 2a).
Therefore, we should first consider the hardness of materials at the small incident angle, both consider plasticity of materials; in a large incident angle, priority should be given to the plasticity of materials, both the hardness of materials.

The impact strenght increase with increasing the p-SBPEPB content before it is not over 8 wt%, when p-SBPEPB content is 8 wt%, the impact strength of materials achieves 0.449 kJ/m2 , which increases nearly one time than that of 0wt% sample (0.227 kJ/m2).
After added the p-SBPEPB, the fracture surfaces of specimens is not so clear- even, and has many holes as (b), (c) and (d), which is the fracture character of tough materials.
So the toughness of materials was improved though the addition small amounts of the LC epoxy resin, and mechanical and thermal properties were enhanced.
The co-curing of liquid crystalline epoxy resin with BPAER can increase the Tg and the impact strength of usually epoxy materials.
