DESENVOLVIMENTO DE APLICAÇÃO WEB PARA CÁLCULO E DETALHAMENTO DE ESCADAS ARMADAS LONGITUDINALMENTE EM CONCRETO ARMADO

Abstract

This work aims to present a web application for the design of longitudinal reinforced concrete stairs. Enabling users with knowledge in the field of civil engineering a free and systematic form of calculations, capable of being performed from mobile devices, desktops and other devices that have an internet browser installed. The purpose is to present a technological interface of free access, responsive, systemic and friendly, where after the insertion of data related to the dimensions of the ladder, it is possible to analyze the information returned for comparison purposes, providing the user with autonomy and agility. The return data show values of the steel areas to be used, allowing the choice of the steel bar gauges and generating a schematic view of the stair frame and its main quantitative. To support the calculation, Brazilian standards 6118 / 2014- Design of concrete structures were used for the design of steel reinforcements, NBR 6120 / 2019- Actions for the calculation of building structures, used to obtain the total load, among others . The ladder model approached was the longitudinal dimension, with one or two flights, where the application presents the following calculation results: total loading of the landing and the flight, maximum moment, dimensionless equation of the bending moment (kmd), position of the neutral line (kx), lever arm (kz), main steel and distribution area. The final detailing contains quantitative, details of the reinforcement and stamp. The composition of this tool was possible from those of programming languages for WEB development, HTML5 for marking display elements information on the page, CSS3, a tool that defines the style and visual part of the project, JavaScript that eliminates static, implementing functionalities real-time editing.
