Why is stability of a prefabricated wooden structure so important

The art of building wooden prefab houses which are stable and strong enough to withstand the tooth of time is defined and dictated by the knowledge and experience of the designer and builder. 

Horizontal stability of a wooden prefab structure (thus also for prefabricated woo0en houses) is always a main issue. Due to the fact that timber inter-connections do not fit exactly (like steel connections do), the structure is extremely sensitive for horizontal movements (displacements). It is not so difficult to horizontally move a wooden framework by hand, unless proper bracings are provided. 

While earthquakes are of minor concern for a wooden house due to flexibility of the wooden structure, the same flexibility is of major concern when a hurricane or a cyclone strikes. The inter-connecting timber parts shall not only be strong enough to absorb the immensely high wind loads, the stability of the house is most important. The high wind pressure loads can easily be absorbed by the tropical hardwoods that we use, however the strength of a wood species does not contribute at all to overall stability. To accomplish this, additional and sometimes far-reaching measures need to be taken (which unfortunately has a negative impact on the price of the house). The second area of concern is the roof structure. Most people believe that it is the wind pressure which may disintegrate a roof. This is a misconception. It is the wind suction which does the major damage. Our engineers have a vast experience in dealing with these problems and know how to solve this.

All prefabricated wooden structures are normally subject to significant shrinkage and expansion caused by temperature and hunidity changes, which are far higher than those experienced for prefabricated concrete structures and prefabricated steel structures. The shrinkages and expansions in wood may have a significant impact on the connections, whether this is done with bolts or screws. These constant shrinkages and expansions will  cause "slackening" of the connections, whereas unexpected and dangerous connection instabilities will occur, which may induce sudden collapses. Modern engineering techniques have been developed and codes been issued over the last decade which take such "slackening" phenomena into account. The codes provide formulae and design advice to cope with these aspects, arriving at safe connections which will remain safe over time. Our engineers are very well familiar with these codes and will properly apply them.       


CONCLUSION:
Relying on the strength of the materials only for a prefabricated wooden house is not sufficient. An proper analysis on the overall stability and the connections shall equally be carried out.  

 

Reviews from Bali Prefab World

"Of so many websites I had visited, yours is one of the best designed and focused. I am truly surprised at the amount of information regarding your company's expertise and experience that you willingly publicized online.

It's little wonder that copy cats are lining up, salivating to emulate your achievements. However they will never be able to muster the expertise in both structural and architecture knowledge that is endowed in the educational background.
Few also will be able to emulate your:
o  business integrity (which is extremely rare nowadays)
o  passion to experiment on what works best and continually incorporating them into your design and end products and
o  using the highest quality raw materials and their treatments thereof to ensure a defect free building that will withstand the     test of time.
Little wonder that your company is the foremost prefabricated wooden house company in Indonesia.
Keep up the great work and may I wish you the very best for years to come
Leong Yue Peng, Malaysia."
