Abstract

This research focuses on the design of a bidirectional reinforced concrete slab for a 5-storey apartment building located on Jalan Pemuda, Semarang, following SNI 1726:2019 standards. The objective is to compare the results of the direct design method (DDM) using Excel with ETABS v18 software, analyzing the accuracy of traditional methods in modern structural designs. The study employed a practical approach, incorporating various design parameters such as beam dimensions, span length, dead and live loads, and material strengths (f'c and fy). The results indicate that although there is a slight difference between the methods, they exhibit similar trends. The study found that increased load leads to higher moments, while larger beams and higher concrete strength reduce reinforcement requirements. However, discrepancies between the methods were observed due to rounding errors in the DDM. The research suggests refining moment calculation techniques and enhancing software tools for more accurate slab designs. The findings are essential for improving design accuracy in both academic and professional practice, particularly for earthquake-resistant structures.

Abstract

The "Guidelines for Planning House and Building Loads", "Minimum Loads for Designing Buildings and Other Structures", "Procedures for Planning Earthquake Resistance for Building and Non-Building Structures", and "Structural Concrete Requirements for Buildings and Their Explanations" serve as the guidelines in order to structural examination planning as well as layout of UGJ Property. Constructural drawing as well as structural analysis programs are accustomed to ascertain the seismic period of the constructure and the internal forces acting on it. The reinforcing steel utilized has a quality of 420 MPa, while the concrete material used has a quality of 30 MPa. A bored pile foundation of 4 m depth was selected based on the planning results.

Abstract

Poured concrete is made based on the standards applied. A table with a practical plate design is a design table that is easy to use in Iapangan and can be used as a reference material for engineers. The plate in question is a conventional double-sided double-reinforced concrete plate according to SNI 1726:2019, the design is used by Iangsung for the calculation of the Ientur moment, and the results are compared with the results of structural analysis using the ETABS 18 application. The results of the calculation using the direct design method and the existing application show almost the same trend, although the values are not much different. Ms. Excel is used as a tool to calculate plate designs with various styles. The variable parameters are the size of the span, the size of the baIok and koIom, the life load, f' c and f'y. The values obtained are presented in the form of niIai moment Ientur and distance of the Age and presented in the form of a calculation table.
