Stress Reduction: A Method of Rehabilitation of Concrete Building

So far we were on different methods of rehabilitation and repair of concrete structure or its specific members to make it serviceable for further use and upgrading its capacity for higher occupancy classifications. We have published different methods of repair and concrete repair materials as well. We will publish more methods of repair and advance repair materials to upgrade a structure with repair.

Now here, in this post we will discuss a method of rehabilitation, that doesn’t need repair work or further construction of new structural elements. This method requires some forms of dismantling just to make it serviceable by reducing stresses in the structure itself.

Partition Wall of Fiberplant for Lightweight Wall used in modern structure
This method provide a relief to structure that are distressed or evaluated as hazardous for upcoming any disaster like earthquake or tornadoes or unexpected loading from any other sources. This is achieved by doing following stress reduction work:

a. Reducing some dead loads and live loads by changing occupancy classes.

b. Sometimes lightweight partitions are chosen to replace heavy weight partition of solid forms. Now-a-days many lightweight materials for partition wall are developed and used in practical cases to achieve this purpose for both new and older structures, rehabilitates in such manner.

c. Providing open spaces in floor by removing inside filler walls. This can be done only when occupancy class is changed.

Struts reduce span of bridge reducing weight of concrete member
d. A method of reduction can be imagined easily is reduction of stories. This provides a great amount reduction in stress and provides a safer column and shear wall if there have any.

Rehabilitation of old structure by ornamental strutse. A lower loading classification can be considered like avoiding some storage facilities, removing or reducing facilities of library, avoiding assembly places in the structure to reduce live loads.

f. Span of beams of structure can be reduced by applying struts etc.

Providing joints of shear movement in location of zero moment in continuous spans of structure is also a good method.


  1. stress reduction management starts with identifying the sources of stress reduction in your life. This isn’t as easy as it sounds. Your true sources of stress reduction aren’t always obvious, and it’s all too easy to overlook your own stress reduction-inducing thoughts, feelings, and behaviors. Sure, you may know that you’re constantly worried about work deadlines. But maybe it’s your procrastination, rather than the actual job demands, that leads to deadline stress reduction.

  2. Very well said. Now I have the ideas and I want to know more about concrete buildings since its part of my job. I work in a Handyman building repair company located here in Gold Coast Qld Au.
