·The models can be used to obtain optimal span of ferrocement channels in different applications (such as roofs and floors) which have unalike maximum loads.In addition,two types of support channels were investigated to determine the optimal tensile reinforcement for the channel in direction of the X and Y axes.Our findings indicated that 1.Q345 Steel,Q345A Q345B Q345C Q345D Q345E Equivalent I beam made from Q345 steel Q345 Steel Properties Q345 steel is a Chinese GB standard Low Alloy High Strength Structural Steel,material density is 7.85 g/cm3,tensile strength is 470-630 Mpa,and yield strength is 345 MPa,it has better properties than Q235.Some results are removed in response to a notice of local law requirement.For more information,please see here.12345Next
