Structural collapse operations cover a wide range of incident scenarios. These incidents can be as relatively minor as a deck or porch collapse resulting in easily accessible victims, or as heavily taxing as a multistory concrete building collapse that entombs hundreds of victims.

Regardless of the collapse scenario encountered, first responders must be familiar with a variety of prevention patterns and associated issues.

In this regard, what do you people think are the process and technogies to prevent structure collapse?

Enable warning system

idea posted by Biranchi Narayan Acharya AGM, Simplex Infrastructures Ltd

Structures are to collapse either at expiry or due to calamities. The design should include mesures so that a structure before collapsing gives enough alert. For example many designers prefer to under reinforce a structure (particularly a tension member). It gives enough alerts such as cracking etc before it collapse. If you over reinforce, the structure will not fail due to tension. But when fails due to failure of compression it collapses suddenly.

Design aspects

idea posted by VIMALAN DIRECTOR, VIRGIN ENGINEERS

Now a days structures failure i.e)sudden collapseĀ are occuring due to earthquake especially in foreign countries,the main reason for this happening is design calculations,cosideration & analysis of safe bearing capacity of soil,earth quake & wind load,bcoz sudden failure of structures in compression member likely buckling of column happens rarely,poor quality or workmanship if we reinforce steel 75% out of 100%, structure will not collapse immediately in tension member or compression member

Thanks&regards,

Is there necessity to revise standards or more focus on implementing them?

In india most of big projects are under goverment area...and every body is currupted.For money they are ignoring to use quality products, to use quality engineers,material testing..etc...

If the government stopped asking for bribes , like children asking for candy , the overheads on contractors and builders would be minimised by far. Proffessional Integrity should be practised at all levels , whether building for the poor or for the rich

I too agree that, but also main reason is Poor Quality assurance is given by higher authority.

Aqueous-based photoresist drying technology

idea posted by Anjali Bhatia Construction-Heavy, Sobha Developers

In many western countries a supercritical drying process was developed to eliminate the capillary forces naturally present during normal drying of photo resist materials. Supercritical carbon dioxide (scCO2), organic solvents and surfactants were used to prevent the collapse of high-aspect-ratio structures. And this has increased the strength of the structure and helps in preventing structure collapse.
