ECLINTELANALYSIS - Lintel Analysis

This part of user manual describes how to use ECLINTELANALYSIS for the analysis of Lintel. ECPlus applications are designed as wizard type which is a step by step guided input procedure. If you are new to ECPlus applications, click here for general guidance.

Prerequisites: The user is expected to have a basic understanding of foundation design concepts.
The minimum input data required to use this application is as follows:

• ❶ Type and Dimensions of masonry wall
• ❷ Openings in wall
• ❷ Load data

Following sections are presented with various input pages of ECLINTELANALYSIS application with descriptions:
