Novel Morphologies of Aluminium Cross-Sections through Structural Topology Optimization Techniques Lukas GREKAVICIUS1,a, Jack Antony HUGHES1,b, Konstantinos Daniel TSAVDARIDIS1,c and Evangelos EFTHYMIOU2,d * 1 Institute for Resilient Infrastructure, School of Civil Engineering, University of Leeds, Woodhouse Lane, LS2 9JT, Leeds, UK 2 Institute of Metal Structures, Department of Civil Engineering, Aristotle University of Thessaloniki, GR 54124, Thessaloniki, Greece acn11l2g@leeds.ac.uk, bcn12jah@leeds.ac.uk, ck.tsavdaridis@leeds.ac.uk, d,*vefth@civil.auth.gr Keywords: Aluminium structural members, novel cross-section design, structural topology optimisation, SIMP technique.
In the last decades, the deployment of aluminium and its alloys in civil engineering fields has been increased significantly, due to the material’s special features accompanied by supportive technological and industrial development.
Conclusions attempt to highlight the advantageous characteristics of aluminium use as well as the potential benefits to the more widespread implementation of topology optimization within the utilization of aluminium in civil/structural engineering.
Successful application of aluminium alloys in structural engineering is connected to its inherent physical and mechanical properties: low density, which allows reduced loads on foundations and easier construction process; excellent corrosion resistance, which reduces its maintenance requirements; and the extrusion process, which allows the production of members with efficient and optimised cross-sections [1].

Research Status of Concrete Strength Theory Based on Stress and Strain Guojun Liu 1, a 1 College of Civil Engineering, Sichuan Agricultural University, China a uontang@163.com Keywords: Concrete, Strength theory, Stress, Strain Abstract: In the civil engineering structures, when concrete structure withstand external loads, internal defects such as micro-cracks gradually developed, eventually will lead to the destruction of the concrete.
Introduction Concrete is a widely used brittle material in engineering, its material composition is uneven, and there is a natural random distribution of micro-cracks and defects in the initial.
The forth is that the form of failure criteria is complex, not conducive to the application in practical engineering.

Simulation and Study on Ultimate Bearing Capacity of Stretcher Bracket for Aeromedical Evacuation Junlin Wan1,a, Kang Lv1, Qinjian Mao1,b, Yuanyuan Zhou1, Shanshan Yang2,c 1The 28th Research Institute of CETC, Nanjing, Jiangsu, 210007, China 2College of Automation, Nanjing University of Aeronautics & Astronautics, Nanjing, Jiangsu, 210016, China awanjunlin@nuaa.edu.cn, b13951657068@139.com, cshanshankitty@nuaa.edu.cn Keywords: Aeromedical Evacuation, Stretcher Bracket, Finite Element Method (FEM), Limit Load, Computer Aided Engineering (CAE).
As the important airborne equipment of casualty aeromedical evacuation, the structure design of aeromedical evacuation’s stretcher bracket not only has to meet the mounting interface in the civil aviation aircraft and meet the medical rescue requirements during the casualty evacuation, and also has the good bearing capacity of limit load.
In the Wenchuan earthquake and the Yushu earthquake, a number of airliner have been emergency modified to transport the wounded patients in the disaster area by the China civil aviation authorities.
Consider the airworthiness of civil aviation, the airborne circumstances and the medical rescue requirements during the casualty evacuation, stretcher bracket not only need to have the good structure design and light weight, and also have the good mechanical properties [3,4].

The calculations and experimental analysis demonstrated the validity with engineering accuracy of using the mathematical model of a short PCT column for engineering calculations and structural analysis.
The early works of the authors [4, 5] addressed issues of rationality of using short PCT columns as resource efficient structures in civil engineering and methodological aspects of quantitative analysis of the stress-strain state of structures taking into account the factors of actual work under load and experimentally determined physical and mechanical properties of PCT materials.

The numerical model was built by the integrated solution system for bridge and civil engineering- MIDAS/Civil.
Fig. 3 shows three dimensional numerical model of the arch-deck bridge built by MIDAS/Civil.
To confirm the calculating precise and fulfill requirement of engineering, the arch is meshed into 58 beam elements in length not longer than 1.0m.
Conclusions The numerical model of reinforced concrete arch-deck bridge was built in details by Midas/Civil.
