RM BridgeV8i - Issues

Hi, 

I have provided a description of two issues found in RM Bridge V8i.

1. When using the Precast Girder Wizard, a roadway eccentricity may be defined under the Load Definition --> SDL --> Roadway eccentricity - input option. This allows for a uniform load to be applied for wearing surface and utilities. The uniform load for wearing surface is applied in the appropriate location and works correctly. Under the traffic tab (still in load definition), a number of traffic and pedestrian lanes may be defined. As the diagram shows in this tab, the location of the lanes is offset from the centerline of eccentricity, previously defined. This however is not true in the model that is yielded from the wizard. The wizard ends up applying the lane loads at the distance offset from the centerline of X-section, rather than the center line of roadway shown (based on roadway eccentricity). This should be resolved in future versions. Pedestrian lanes are referenced from centerline of X-section and are therefore correctly defined in the model.

2. Under Properties --> Reference Sets --> a series of temperature points for temperature gradient analyses can be viewed for a selected part. RefSetType Temp.point, AttrSet (typical): w2_Temp3.

If we select the i-icon ("graphical input of additional points"), we can view the temperature points and connecting lines between points that show the temperature gradient for a part X-section. In the display window (US Units), the distance between points are shown correctly in ft (under Distance), and degrees Fahrenheit under TMP. If we select the i-icon again in this window (“graph with temperature gradient”) I have observed one of two results.

a)    An error for the distance and an incorrect temperature gradient that shows up in degrees Celcius.

b)    Or distance in meters (incorrect), and again a temperature gradient that is in degrees Celcius. Furthermore, the graphical representation of the temperature gradient (in Celcius) is based on the incorrect gradient shown in new popup multiplied by an additional conversion factor between Fahrenheit and Celcius. 

This being said, the definition for temperature gradient in the analysis appears to be correct. However, this should be further investigated.

Thanks,

Thomas
