Alp
Analysis of behaviour to inform the design of laterally loaded piles.
What is Alp
Laterally loaded pile analysis
Oasys Alp enables analysis of individual piled foundations. Alp predicts the pressures, horizontal movements, shear forces and bending moments induced in a pile when subjected to lateral loads, bending moments and imposed soil displacements.
Structural and geotechnical engineers collaborate using an iterative workflow by combining outputs from Alp with Oasys Pile for specified capacity and settlement calculations that are used as inputs in Oasys AdSec to inform pile cross section characteristics.
Core capabilities
Modelling conditions
Lateral loads or bending moments and restraints can be applied at any location down the pile.
Custom options
Non-linear soil properties can be modelled using predefined or user-inputted P-Y curves. Stiffness of sections can be calculated by inputting section geometries and materials.
Modelling soil behaviour
The soil load-deflection behaviour can be modelled either assuming Elastic-Plastic behaviour, or by either specifying or generating load-deflection (i.e., P-Y) data.
Multiple analyses
Alp enables single-stage loading scenarios and push over analysis.
Partial factor analysis
Apply partial factors according to EC7, SLS or apply custom combinations.
Code-compliant concrete design
Model concrete pile sections to a range of design codes including European, Indian, British and American standards amongst others.
Automation ready
Use Alp in automation workflows using the COM interface and JSON file format.
Why choose Alp
Alp is the trusted solution for civil and geotechnical engineers seeking efficient, accurate foundation design.
