Hi bridge experts,
Where the numbers in Table A13.2-1 (AASHTO LRFD of any version from 1998 to 2010) came from? There are some commentary for the load distribution lengths, however there is no comment for forces, eg Ft, Fv, Fl.
Are there any relations between test levels in NCHRP Report 350...
Hi people,
In ASTM F2787-09, the serviceability condition requires that the deflection (change in rise and span) under service loads be limited to 2.5% of the nominal rise and span. I am not familiar with ASTM. Questions:
1. What included in the service loads? What modulus of the arch...
Thanks bridgebuster for your response.
You're right, the selection of a railing is based on a risk assessment in which traffic volume is considered. I have no problem with the design of the railing, however, the procedure for determining the appropriate test level for a bridge site is not clear...
Hi bridge engineers,
AASHTO specification 'Guide Specifications for Bridge Railings' 1989 includes a procedure for determining an approproate performance level for a given site. This procedure is not included in NCHRP Report 350. Please advise:
- What documents or AASHTO specifications also...
Thanks JBeng00, for your reply.
I am sorry that I did not state the problem clearly. I mean modelling the bridge lane load.
In the SG manual it says: "This module does not generate loads from static sources such as bridge lane loads. They must be input using the normal load input tools in...
Dear Aussie bridge engineers, I am new to Space Gass. I am trying to run a grillage analysis but cannot model the uniformly distributed lane load. Could any one explain to me, please? I appreciate any help.
