Diseño y simulación estática de una estructura para andamios reforzados modulares en izaje de perfiles hasta 1t

Abstract

The purpose of this technological proposal is the design and simulation of a reinforced modular scaffolding for lifting beams up to one ton, analyzing design criteria based on the INEN standards that govern Ecuador, where the loads to which it is going to be evaluated are mainly to submit the structure in this case wind loads, live loads and point loads, once the pertinent calculations were made based on equations used in structural calculation, we proceed to the selection of profiles using DIPAC manuals where it is chosen for the tubular elements 3 mm and 2 mm thick tubes, on the other hand, for elements that resist punctual loads, IPE 140 beams are used, which adapt to the slenderness criteria, while through calculations it is verified that they are within the acceptable ranges so that the structure does not collapse, having a slenderness of less than 100. Through the investigation and selection of types of scaffolding, a geometry is designed where it is sought that all the elements work in the same proportion to support the loads to which the structure will be subjected, in the simulation using the SAP 2000 software several results are obtained. among which he has focused mainly on efforts, reactions, deformation, and stress of the structure. The maximum stress value was obtained in an element of 16.65 𝐾𝑠𝑖, the reactions in its supports reach a maximum value of F1=5.06kN; F2=3.84kN; F3=29.2kN, on the other hand, its deformation does not exceed 3 to 4 mm in displacement from its initial position, and finally the maximum stress of the most critical element is 65339.21 kN/m2. However, through design and simulation it is concluded that a rigid structure capable of supporting loads of up to one ton for beam hoisting is obtained.
