Design of masonry building?

Question

Hi i need to analyse a masonry building for seismic loads and to provide adequete retrofiting measures. I studied IS1905, it gives detail for design but i need some information regarding analysis.

Answer 1

The UBC standard in the U.S. is mostly obsolete, only a few jurisdictions are still using it, because it hasn't been updated since 1997.

The U.S. Standard for seismic is ASCE 7-02 or 7-05 or 7-98, (via, if you wish, IBC 2000, 2003, or 2006) depending on what code is relevant to the jurisdiction. In India (if you're in India), you need to find out what that equivalent is (Perhaps Eurocode? I have no idea), but that will give you more insight into the code required analysis, including force distribution.

Barring that, the most relevant item in seismic analysis is the weight of the building elements, and their connections, start finding out what the floor weighs, is there a sprinkler system, carpet, ceiling tile, how much the structural floor weighs, wall partitions inside the building, etc. When it comes to determining adequacy, you also need to find out how floors are connected to walls, how walls are reinforced (I hope they aren't cyclopean or unreinforced walls, because those will probably not meet current code unless you are in a very low seismic zone, I don't have any idea how India's seismic zones lie, I just know Bam in (Iran?) had a bad earthquake a few years ago.

Sorry I can't be of more help.

Answer 2

Get a copy of the latest edition of The Uniform Building Code, or some other building code which contains a section on seismic design requirements

Answer 3

SIESMIC ANALYSIS IS A PART OF STRUCTURAL ANALYSIS. YOU HAVE TO STUDY BOOKS ON SAME . SOFTWARES ARE GENERALLY USED FOR SIEMIC ANALYIS. ONE SUCH SOFTWARE FROM UNIV. OF BERKLEY IS SAP 2000. LOOK FOR TUTORIALS IN THE WEB FOR SAP.
