About This Spreadsheet
This spreadsheet is for designing overhead bridge crane crane load and crane runway beam as per AISC LRFD 2010, ASD 2010 and ASD 1989 code
The spreadsheet is capable to design up to 2 cranes running in the same aisle at the same time.
For crane runway beam section, the user has option of
AISC W or S section
AISC W or S section combined with cap plate
AISC W or S section combined with cap channel
Any custom W or W and C combined section
The custom section option gives user great flexibility to select the crane runway beam section and optimize the design.
The spreadsheet also outputs the crane loads imposed on building column for user to relay to other structural analysis software for building structural analysis
The spreadsheet can design both top running and underhung overhead bridge crane runway beam

No of Crane In The Same Aisle
The program is capable to design up to 2 cranes running in the same aisle at the same time.
User can choose the no of crane in one aisle here.
Crane Rated Capacity
The unit for this input is
US Ton
!
1
US Ton
= 2000 pounds = 2.000 kips
1
Metric Ton
= 2204 pounds = 2.204 kips
1
Metric Ton
= 1.102
US Ton
If the crane capacity is in
Metric Ton
, multiply 1.102 to convert it to
US Ton
for input here.
If it's Underhung crane, the max. crane rated capacity is normally limited to 10 US Ton.

Runway Beam Section Type
W Shape With Cap Channel - AISC Table 1-19 Sect
Sections are only limited to sections listed in AISC Steel Construction Manual Table 1-19 .
W Shape With Cap Channel - Any W & C Sect Comb
Sections can be combinations of any W shape and C channel user selects from the list.
Runway Beam Custom Section Preliminary Check
This section check is only applicable when custom section is chosen.
The crane runway beam section shall be set in such a way that the top flange is wider and thicker than the bottom flange, but when doing this, users shall avoid the case like A
2
+ A
3
< A
1
, where
A
1
= top flange area
when there is cap channel, A
1
= top flange area + channel section area
A
2
= bottom flange area A
3
= web area
When A
2
+ A
3
< A
1
, the plastic neutral axis moves to top flange range and it's not recommended by the program.
The program will flag
NG
in this check when A
2
+ A
3
< A
1
.
User can increase the bottom flange and web thickness to pass this section check.
CMAA Crane Service Class
CMAA 70-04 Specifications for Top Running Bridge and Gantry Type Multiple Girder Electric Overhead Traveling Cranes
Page 10~11
Class A Standby or infrequent service
Class B Light service
Class C Moderate service
Class D Heavy service
Class E Severe service
Class F Continuous severe service
Most cranes are under Class C category.
The crane service class will impact the serviceability criteria in crane design.
