1. Steel Member Design as per EN1993-2:2005 Steel member design as per EN1993-2:2005 has been implemented for the following checks:

Classification of a cross section Ultimate Limit State Check

• Design Tension Resistance, Design Resistance for Uniform Compression • Design Resistance for Bending • Design Shear Resistance, Shear Buckling Resistance • Combined Effect of “Bending and Shear”, “Bending and Axial Force”, and “Bending, Shear and Axial Force”

Serviceability Limit State Check: • Vertical deflections, Horizontal deflections

Partial Safety Factor can be defined by the user directly. Default value of γm0 and γm1 is “1.0”. Applicable section types are L, C, H, T, Box, Pipe, Rectangle, Round, Double-L and Double-C types. Also tapered section is supported.

2. RC Beam Design as per EN1992-2:2005 In the previous version of midas Civil, only RC column design was available as per EN1992-2:2005. In the new version, RC beam design has been

added for the following checks: Ultimate Limit State Check

• Moment Resistance • Shear Resistance

Serviceability Limit State Check • Stress for Cross Section • Crack Width • Vertical deflections, Horizontal deflections

Eurocode Recommended, British and Italian National Annex are available. It can be selected in Concrete Design Code dialog box. Partial Safety Factor can be defined by the user directly. Applicable section types are Rectangle and T-section.

3. Improvements on Moving Load Analysis as per EN1991-2:2003 Load Model1 and Footway loading can be applied simultaneously. Also the uniform load value for footway can be entered by the user directly.

User defined special vehicle for straddling is newly added. During the analysis, the wheel spacing will be applied as the value specified in Traffic Line/Surface Lanes dialog box. By converting the load into static load in Moving Load Tracer, the exact wheel spacing entered in “Wheel Spacing for Static Load” option box can be applied. Variable axle spacing can also be considered by entering the minimum and maximum spacing.

For Load Model3 “1200/150/200”, “1500/150/200”, and “1800/150/200” vehicles, the user can choose the desired vehicle to be considered in analysis. In the previous version, the program always considered two vehicles in order to find the more critical vehicle results. When two or three vehicles are checked on, the most critical vehicle will be applied to obtain the moving load analysis results.

For the easier selection, the Load Model3 vehicles have been separated from the “Vehicular Load Type”.

In the previous version, when LM1&3 Multi(Straddling) load model was selected in Moving Load Case, the lanes defined as Straddling Lanes were always determined as Lane Number 1 and 2. In the new version, regardless of the straddling lanes, the most critical lane is determined as Lane Number 1.

For Fatigue Load Model3 (Two Vehicle), spacing between two vehicles is changed from 40m to 31.6m as specified in EN1991-2.

In the automatic generation of load combinations as per Eurocode 0, when traffic load is a Leading Variable action, frequent values of traffic loads should be used for Frequent Combination. In the previous version, the program could not classify the traffic loads as Characteristic Value and Frequent Value. In the new version, the user can specify the frequent value of traffic loads in “Assessment of Groups of Traffic Loads” dialog box.

4. Improvements on Moving Load Analysis as per Canadian Specification

Standard Vehicular Load as per Canadian Specification

For BCL-625 Truck and BCL-625 Lane vehicle loads, the option “Increment of Axle Spacing for Variable Length” has been newly added.

In the previous version, the incremental spacing of variable length referred to the “Influence Generating Points” option in Moving Load Analysis Control Data dialog box. Since analysis time is highly affected by the variable length, a separate option to control variable spacing has been added.

Minimum value between “the entered incremental spacing value” and “the element length/2” will be applied during the analysis.

When Moving Load Code is specified as Canada, Analysis Method option (Exact, Pivot, and Quick) can be selected in Moving Load Analysis Control Data. In the previous version, “Exact” option was always applied.

When the section offset of tapered section is specified as top or bottom of the section, the member forces and stresses can be obtained along with the local axis parallel to the offset line. This option is useful when the user wants to obtain the vertical forces parallel to the gravity direction in tapered section.

6. Option for Fixed Support in Point Spring Support Stiffness of the selected component is automatically entered as very large value (SDx, SDy, SDZ: 1e+13kN/m, SRx, SRy, SRz:

1e+16kN/m) so that it can behave like simple support. This option is useful when the user wants to consider the spring stiffness only in a certain direction without defining spring stiffness at the same nodes additionally.
