Building collapses are attention grabbers. Recent building collapses, in China, Ahmedabad and Hyderabad, were in news, we all felt this, and shouted hoarse. These collapsed buildings were under construction. Most such collapses recently in news, at least I have found, were under construction. This is bad.
In my opinion I would like to recall IS 875-Part 5 which is a code, please note just a 'code', a probable prescribed way of conduct in this country, stating this in its clause 5.1. Can a code get simpler?
I am breaking and rewriting clause 5.1. below which is a few sentences. Please comment or add if you can.
5.
STRUCTURAL SAFETY DURING CONSTRUCTION
5.1.
All loads required to be carried by the structures or any part of it, due to storage or positioning of construction materials and erection equipment including all loads due to operation of such equipment, shall be considered as erection loads.
Proper provision shall be made, including temporary bracings to take care of all stresses due to erection loads.
The structure as a whole and all parts of structure in conjunction with the temporary bracings shall be capable of sustaining these erection loads without exceeding the permissible specified in respective codes of practice.
Dead load, wind load and such parts of imposed load as would be imposed on the structure during the period of erection shall be taken as acting together with erection loads.
