IntroductionĬoncrete is a typical heterogeneous composite consisting of aggregate, cement paste, and void. The results of the three-dimensional meso-scale numerical analysis method agree well with the experimental values of steel fibre concrete beams. A steel fibre bond slip is considered in an equivalent manner using the von Mises model.

The constitutive concrete model adopts the total strain crack model of concrete. The fibre geometry model program generated by a secondary development ANSYS program was exported to midas FEA for analysis. Steel fibre reinforced concrete (SFRC) has been widely studied experimentally and numerically in recent decades. Load Model 1 should be applied to each notional lane and to the remaining area.Concrete is a heterogeneous composite consisting of aggregate, cement paste, and void. Load > Load Type > Moving Load > Moving Load Cases > Add Recommended values of factors for road bridge Load Model 1 (LM1) : Concentrated and uniformly distributed loads, which cover most of the effects of the traffic The user can directly change the Adjustment Factor given in Standard Name : EN 1991-2:2003 RoadBridge

If the user is modeling a bridge having multiple girders, the Crossīeam type is recommended for vehicular load distribution.įor example, an axle load of 100kN is located as shown below. To the girders via cross beam elements defined as a Cross Beam Group. When using Cross Beam type, the eccentricity is used only for locating the lanes from the line lane elements. The distribution of the loads onto the cross beams will not be considered.Ĭross beam: Apply the traffic loads to the cross beams. Even though the lanes can be located on cross beam elements, if the lane element type is selected, then When defining lanes by the lane element type, the vertical load components (vehicle loads) and the moments due to the eccentricity areĪssigned only to the line lane elements. Lane element: Apply loads to the traffic line lane elements reflecting the eccentricity. Load > Load Type > Moving Load > Traffic LineĤ.
