ในการพิจารณาข้อดีและข้อเสียระหว่างค

In order to determine the pros and cons between prestressed concrete and reinforced concrete. To consider the criteria that will be used to compare the steel. First, there is the material used in prestressed concrete, we need high strength steel. This is so the net pressure after pressure loss, also have higher because there is high creep of concrete and reinforced concrete are shrinking less than normal. The use of high strength concrete to resistance units, high adhesion occurs when pressure on lever pull shot of iron or to resistance units pressure due to a strong shot in the beam anchorage device, while the soft strength.

In consideration of the advantages and disadvantages between concrete and reinforced concrete. Steel to consider the criteria to be used for comparison. The first is the material used in steel high strength concrete we need. In order to pressure the net after a loss, then there are high because in addition to high strength concrete creep and shrinkage of concrete were less than normal. The use of high strength concrete is required to withstand the stresses that occur when shooting high adhesion strength in drawn steel beams or to resist the pressure because the device while taking a strong anchorage in prestressed beams later.

In considering the advantages and disadvantages between prestressed concrete, and reinforced concrete. To consider the criteria to use steel are compared. The first is the materials used in prestressed concrete, we need to use steel is high.There is high. Because the high strength concrete creep and shrinkage are less concrete is ปกติแล้ว.Anchorage while taking force in prestressed beams later.
