Cap channel or plate yield strength f cy = ksi CMAA crane service class = moderate service Vertical load impact factor = Crane side thrust load option = Crane side thrust load can be calculated using one of the following 4 options Option 1 Hs = 0.2 (Lifted Load+ Trolley/Hoist Wt) Option 2 Hs = max of 0.2 (Lifted Load+ Trolley/Hoist Wt) 0.1 (Lifted Load+ Entire Crane Wt) Option 3 Hs = max of 0.2 (Lifted Load+ Trolley/Hoist Wt) 0.1 (Lifted Load+ Entire Crane Wt) 0.4 Lifted Load Option 4 Hs = 2.0 x Lifted Load as side thrust for stacker crane. 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. 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. CMAA Crane Service Class CMAA 70-04 Specifications for Top Running Bridge and Gantry Type Multiple Girder Electric Overhead Traveling Cranes Page 1011. 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.

Geometry, material, cross-section, action and imperfection data is entered in clearly arranged input windows: Geometry. Quick and comfortable data input.
Definition of support conditions based on various support types (hinged, hinged movable, rigid, and user-defined as well as lateral on upper or bottom flange). Optional selection of warping restraint. Variable arrangement of rigid and deformable support stiffeners. Possibility to insert releases CRANEWAY Cross-Sections. I-shaped rolled cross-sections (I, IPE, IPEa, IPEo, IPEv, HE-B, HE-A, HE-AA, HL, HE-M, HE, HD, HP, IPB-S, IPB-SB, W, UB, UC, and other cross-sections according to AISC, ARBED, British Steel, Gost, TU, JIS, YB, GB, and others) combinable with section stiffener on the upper flange (angles or channels) as well as rail (SA, SF) or splice with user-defined dimensions. Unsymmetrical I-sections (type IU) also combinable with stiffeners on the upper flange as well as with rail or splice.
Actions It is possible to consider actions of up to three simultaneously operated cranes. During the calculation, crane loads are generated in predefined distances as load cases of crane runway. The load increment for cranes moving across the crane runway can be set individually.
The program analyzes all combinations of the respective limit states (ULS, fatigue, deformation, and support forces) for each crane position. In addition, there are comprehensive setting options for specification of the FE calculation such as length of finite elements or break-off criteria. The internal forces of a crane runway girder are calculated on an imperfect structural model according to the second-order analysis for torsional buckling. All results are arranged in result windows sorted by different topics. The design values are illustrated in the corresponding cross-section graphic.
Design details cover all intermediate values. General Stress Analysis CRANEWAY performs the general stress analysis of a crane girder by calculating the existing stresses and comparing them with the limit normal, shear and equivalent stresses. Welds are also subjected to the general stress analysis with regard to parallel and vertical shear stresses and their superposition. Fatigue Design Fatigue design is performed for up to three cranes operating at the same time, based on the nominal stress concept according to EN 1993-1-9. In the case of the fatigue design according to DIN 4132, a stress curve of crane passages is recorded for each stress point and evaluated according to the Rainflow method. Buckling Analysis Buckling analysis considers the local introduction of wheel loads according to the standard EN 1993-6 or DIN 18800-3. Deformation Analysis Deformation analysis is performed separately for the vertical and horizontal direction by comparing the designed displacements with the allowable values.
You can individually specify the allowable deformation ratios in the calculation parameters. Lateral-Torsional Buckling Analysis The torsional-flexural buckling analysis is performed in accordance with the second-order analysis for torsional buckling considering imperfections.
The general stress analysis has to be fulfilled with the critical load factor smaller than 1.00. As a result, CRANEWAY displays the corresponding critical load factor for all load combinations of the stress analysis.
