Earthquake that came in this era and many victims, mainly due to the collapse of buildings should make us all to think. Is all this happened due to the earthquake magnitude?, Or is due to the quality of buildings that are not standard? Or from both?
Fulfillment of the quality of buildings, especially in the building structure is not negotiable additional fee for building earthquake-resistant construction standards when compared with the result that would occur if we are not going to mean sloppy.
Construction actors, both implementers and planners and the public should begin to consider and use of earthquake-resistant building standards in all construction activities to anticipate when the earthquake occurred, resulting in no casualties in vain for an economic reason.
Damage to the building with a spouse without the retrofitting construction is generally caused by:
- Building the relative weight
- Building is not ductile
- Building is not able to resist the pull caused by the earthquake forces working in the field direction perpendicular to the wall.
Damage to the building with a construction partner is generally caused by:
- There is no anchor for the binding between the walls with a strength element (columns and beams).
- There is no element of retrofitting to the extent of wall ≥ 6m2.
- Detail reinforcement that is not true at the meeting of reinforcement elements.
- The quality of the concrete beam and column frame construction is very low.
- Diameter and total cross-sectional area of reinforcement is set too small, the distance between the cross bar is set too large.
