properties of Gausian Weight in element nonlinearBeamColumn

[m630309]

Hello. I want to ask a question about the properties of Gausian Weights in element nonlinearBeamColumn. I used the nonlinearbeamcolumn elements by 5 integration points along elements. In The OpenSees Command Language Manual had been detailed "The integration along the element is based on Gauss-Lobatto quadrature rule (two integration points at the element ends)". whereas this preamble is scant.what is the w1,w2,w3,w4,w5 (Gaussian Weights) and relative status of integration points along nonlinearBeamColumn element.

Thank you for your help.

Here is a link to the Gauss_Lobatto quadrature rule where you can find the information you are looking for:
