Abstract

The development of technology in the last few years can not be denied that it has developed very rapidly. In building construction, reinforced concrete beam and columns calculations also utilizing that technology development. Input data used to calculate reinforcement of beam and column are material property, section property and internal forces. Calculation of reinforcement beam using quadratic equation method and reinforcement column using Newton-Raphson method and divided-by-two method.Calculation results are flexural reinforcement As (longitudinal compression area) and As' (longitudinal tension area), shear reinforcement Av (transversal area) and S (distance of  Av), torsional reinforcement Avt (transversal area due to torsional and/or shear), S (distance of Avt), Along (longitudinal area due to torsional buckling), column circular reinforcement Atot (total of longitudinal area), column rectangular two faces reinforcement Atot (total of longitudinal area), column rectangular four faces reinforcement Atot (total of longitudinal area), column biaxial reinforcement Atot (total of longitudinal area).   The program determines As, As' and Atotal, the code is written using the Texas Instruments programming language, so that it can be applied to smartphones. Smartphone and manual calculation, for all cases not more than 5%, the calculation using Texas Instrument is accurate.

Abstract

Dalam analisa struktur, ada dua macam cara untuk menyelesaikan yaitu analisa linear dan non linear. Untuk masalah linear penyelesaiannya dapat dilakukan dengan metode konvensional seperti: Cross, Takabeya dll. Sedang untuk analisa non linear ada dua macam type yakni  : material non linear dan geometri non linear. Teori Large Deflection termasuk kategori Geometri Non Linear, dimana defelction yang terjadi adalah cukup besar, yang dapat mempengaruhi perubahan geometri strukturnya. Metode Analisa Matrix dikembangkan dari sifat linear dari suatu struktur. Untuk menyelesaikan masalah non linear, pembebanan diubaha menjadi beban yang lebih kecil, sedang batasan permayalahan yang dibahas adalah analisa Plane Frame, material linear elastis, shear deformasi diabaikan, thermal effect diabaikan, element adalah prismatis.   For linear problems, conventional methods such as Cross and Takabeya can be used to solve them. Nonlinear analysis, on the other hand, involves two types: nonlinear material and nonlinear geometry. Large Deflection Theory falls under the category of Nonlinear Geometry, where the resulting deflection is large enough to affect the structural geometry. The Matrix Analysis method is developed from the linear nature of a structure. To solve nonlinear problems, the load is converted to a smaller load. The problem constraints discussed are Plane Frame analysis, linear elastic material, shear deformation is ignored, thermal effects are ignored, and the element is prismatic.
