This paper introduces the construction technology of steel bar truss deck with Tianjin Museum engineering examples.
This paper presents the construction technology of steel bar truss deck with an engineering example.
The engineering floor need to stagger laying, so measuring the line then hoisting the board which will need to laying when laying ,and start with the starting point for laying, four pieces of a single unit, then laying adjacent four board at the disconnect.

Numerical simulation method of tensile behavior of glass fiber laminates Shaochong Yang1, a, Jianhui Zhang1, b 1 College of Civil Engineering & Architecture, Hebei University, Baoding, Hebei, 071002, China ayangshaochong@hbu.edu.cn, bhbuzjh@hbu.edu.cn Keyword: glass fiber laminates; numerical simulation; mechanical behavior; stress; strain Abstract: Based on the structural characteristics of glass fiber laminates, a novel finite element numerical model of the laminates was proposed and established with ANSYS software.
Introduction Glass fiber laminates with light weight, high specific strength, corrosion resistance, and the other advantages of strong mechanical performance, are widely used in wind blade, aircraft, spacecraft and civil engineering structures.
And, the use of the laminates in bridges and other civil engineering structures has received considerable attention in recent years.
