Your Questions About Building Analysis And Design

Mary asks…
Design of masonry building?
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.

aplus answers:
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.

Michael asks…
Programming/Design: What to learn first?
The following is a list of courses that I can take to help me learn basic functions of web design, database design and building servers. Is there a better order to take them in?
Web design and Graphics
Object oriented analysis and design
Dynamic HTML
TCP/IP
XML
Java
AJAX
Visual Basic C
C
PERL/CGI
IIS 6
Windows Server
PHP and MYSQL
SQL
Oracle
TY!

aplus answers:
I’d go with Dynamic HTML (webpage design), then php & mysql this will cover some database design stuff that can be implemented within your webpages.
You will want SQL as well if your working with databases.
For building servers, Windows Server, IIS6. Skip the TCP/IP, this is networking protocols. Perl and CGI may be useful for web server programming also.

Joseph asks…
Is there any analytical ways to increase design loading on structure. It is difficult and time consuming?
but it is less expensive than actually strengthening the members. The building owners resist paying for extensive analysis and the design fees are not sufficient to permit detailed investigation. Comment on why this is so.

aplus answers:
Either increase the size of the members, increase the number of members, or reduce the load.
I see no other options.
If you are using wood, you could switch to steel, or use glu-lam wood headers or beams (but they are more expensive).
Building owners will have to suck it up, if they want their building inspected and approved for public or private occupancy.
Life is cruel, but deadly if codes are not complied with.
There is a reason why they are there.

Sandra asks…
Why do building owners resist paying for extensive analysis?
and the design fees are not sufficient to permit detailed investigation. Commend on why this is so.

aplus answers:
Owners only understand that the building can stand on its own
that the engineer who construct it is also responsible
that 99 % of the building is safe for a time that
that whenever there is an earthquake damages, insurance is justified
that when big fire will occur, investigation will focus on where the fire started.
If it is a typhoon that destroyed the building, other houses also are destroyed. . I t is just natural
