gvd-openseespy 0.1.0

Modified OpenSeesPy distribution including the GVDHysteretic uniaxial material

GVD-OpenSeesPy

GVD-OpenSeesPy is a modified OpenSeesPy distribution that includes the GVDHysteretic uniaxial material developed for modeling the cyclic behaviour of dowel-type timber connections.

Installation

Install with:

pip install gvd-openseespy

Usage

Use the package as:

import gvd_openseespy.opensees as ops

ops.wipe()
ops.model("basic", "-ndm", 1, "-ndf", 1)

# Define the GVDHysteretic material using the required parameters
ops.uniaxialMaterial("GVDHysteretic", 1, ...)

Current support

This first release currently supports:

• Windows 64-bit
• Python 3.13

The package includes a precompiled OpenSeesPy binary so users do not need to compile OpenSees from source.
