There are some questions about these three software design tools
1- Which software program is better for design high-rise building?
ETABS is mostly used for analysis and design of building, whereas different structures (i.g. bridges, tower etc) can
be modeled in SAP2000 while the application of this software is more for structural analysis than structural design.
Also, SAFE is a specialist software for analyzing and designing slabs and foundations.
2- Why should I use different software program for design accurate building?
Using different software for building design offers a complete approach, using each tool's strengths. For example,
ETABS is great at studying movement, SAFE focuses on floor design, and SAP2000 is flexible. Using more than one
program makes designs more accurate by looking at different parts of how buildings work, making sure they're
strong and dependable.
3- In Iraq which software program most using?
In Iraq, when it comes to designing and analyzing buildings, the top choice is ETABS, followed by SAFE, and then
SAP2000. People tend to think that if something is expensive, it's better quality. So, considering the cost of each
software program, these are the ones most commonly used for building design in Iraq [5].

- 3. 1.Introduction 1.1 About the Structure The building we're talking about here is going to have ten floors and will be used for people to live in. It's going to be built in Erbil. The kind of structure it is called an RCC-Framed structure, which means it's made of reinforced concrete. This type of structure is strong and sturdy, which is important for buildings that have many floors like this one. We need to make sure it's designed and analyzed properly to make sure it's safe for people to live in. 1.2 Analysis Procedure The structure has been modeled, analyzed, and designed using computer software such as "ETABS v21.0.0," "SAFE v21.2.0," and "SAP2000 v25.1.0." These software programs boast excellent analysis and design capabilities, which have been confirmed through verification problems included in their packages. They operate based on the Finite Element Method (FEM) and require the structure to be modeled using finite elements 3

It's interesting because each program gave us different answers, showing that they work in different ways. In our presentation, we'll show you the results from each program and compare them carefully. This will help us understand which program is better for different engineering tasks.

In Revit, we'll get detailed reinforcement info to finish our project. When we've gathered all the needed data and analyzed the reinforcement, our work will be done. Using these different software together helps us work accurately and quickly, making sure we deliver good results on time. ETABS

- 122. 122 5.4 Discussion ETABS is really good at figuring out how tall buildings handle strong forces like earthquakes and wind. SAFE is focused on analyzing and designing concrete slabs and foundations, which are really important parts of tall buildings. SAP2000 is a flexible and versatile software that helps engineers analyze high-rise buildings. It offers many different ways to study how the building behaves under different conditions o The bending moment results for live load (LL) obtained from three different software tools for slab design vary due to differences in their analysis methods and features: SAP2000 (in component M11) Mmax=-3.6 kN.m/m ETABS (in component M11) Mmax=-3.2 kN.m/m SAFE (in component M11) Mmax=-3.6 kN.m/m from SAP2000 SAFE (in component M11) Mmax=-4 kN.m/m from ETABS o The results for the axial force (LL) in the base column vary across three different software design tools. SAP2000 Pa=-151.2 kN ETABS Pa= -156 kN SAFE Pa= -155.5 kN
