    Abstract

    The aim of the project is to critically compare two manual methods for lateral load analysis of a multi-storey building frame and compare them with the result from a computer analysis.
    The manual approximation methods chosen to compare with the computer software were the portal method and the cantilever method. The computer software package used was LUSAS analysis. The results from the portal and cantilever method for lateral load analysis of a multi-storey frame were compared with the results from LUSAS computer software. The results being compared were the bending moments, shear forces and axial forces within the structure, determining the similarity’s, differences and limitations to each method, also outlining the best time to use each method.
    The portal method predicts the shear in the columns and is most accurate for short frames. The cantilever method estimates the axial force in the columns, was more tedious to carry out and produces a greater average difference then the portal method. Approximation methods of analysis are used in the early stages of the design as they do not require geometrical or material properties for the analysis. They can also be less time consuming and are commonly used in practice to estimate member properties.
    The project contributes to existing knowledge as it outlines the portal and cantilever method for lateral load analysis of multi-storey building frames and compares the differences in two manual methods and the results from LUSAS computer software analysis. By using three different methods to analyse the same frame a better comparison of the methods can be made.
