performance analysis

[[email protected]]

dear forum officials, my question is from the municipality, a building with the existing basement-ground and 1st normal floor will be designed as masonry and when it is covered with a steel roof, the performance analysis of the building is requested. The loads determined by the steel roof analysis will be applied to the last floor columns. Will the roof load be defined by entering all floors, including the foundation, or will it be sufficient to transfer the roof load by entering the column beam and floor of the last floor? Thank you in advance for your interest. NOTE: It will not be possible to adjust the amount of iron in the existing static project of the building for 10 years and to save the columns.

Hello,

my question is that the top of a building with the existing basement-ground and 1st normal floor from the municipality will be designed as masonry

New column instead of masonry floor on an old building -Defining a beam system may be a more appropriate solution. The existing building can be defined with its own material information, and the new floor with the new material information, and performance analysis can be made.

When covered with a steel roof, a performance analysis of the building is requested. Loads determined by steel roof analysis are effective on the last floor columns

You can effect the roof loads on the columns you have just defined.

The building is 10 years old, it is not possible to adjust the iron amount in the existing static project and save the columns.

Depending on the performance level of the building, you may need to strengthen the system. You can add Reinforcement Curtains to appropriate places.

Mr. Hakan, thank you for your attention. My main question is whether I should only enter the last floor (except for the foundation and ground floor) and have the roof load on the columns affect my roof load.

My friend, first calculate the loads of the masonry building, add them on the reinforced concrete part and analyze. Here you can see the state of the reinforced concrete part. Then analyze the masonry part separately and you will see the state of the masonry part. Other friends say that such a building cannot exist, technically correct, but we live in Turkey. After the third floor, strange structures such as consoles (there are structures made by placing columns) are built on the adjacent side building in order to gain space. You have to make two separate calculations and convince the friends in the municipality.
