CALCULATION OF PRESTRESSED REINFORCED CONCRETE FARMS BY FINITE ELEMENT METHOD TAKING INTO ACCOUNT PHYSICAL NONLINEARITY
Abstract. Considered is the method of calculation of prestressed reinforced concrete farms taking into account physical nonlinearity. Prestress is modeled due to the thermal effect on the core crab. Rating formulae, allowing to define the temperature value necessary for the achieving the given prest...

| description | Abstract. Considered is the method of calculation of prestressed reinforced concrete farms taking into account physical nonlinearity. Prestress is modeled due to the thermal effect on the core crab. Rating formulae, allowing to define the temperature value necessary for the achieving the given prestress level are givenThe nonlinear calculation algorithm used by the authors is based on the earlier developed and implemented into the computer system PRINS method of physically nonlinear calculation of reinforced farms without prestress of the armature. As an example is considered the calculation of prestressed farm on two supports with polygonal contour of the top belt. Load is applied in the form of concentrated forces in the top belt units. For all cores is accepted the same cross section area and the same ratio of reinforcement. Thermal loading was carried out for one step and load was applied in parts equal the one tenth of the nominal value. Calculation results are analyzed and presented. |
