cracking load การใช้

• Cracking loads of sfrc tree - pile caps and their calculation
• ( 2 ) the crack load increases with the increase of the amount of the prestressing steel or the tensioning stress
• The stress and strain states of concrete and reinforcing bars , initial crack load and crack development are preliminarily understood
• The crack load of the frame applied horizontal load and vertical load is larger than that of the same frame applied vertical load only
• Influence of the amount of the prestressing steel and the tensioning stress to the crack load of the beam is greater than that to the crack of the column
• Using two different finite element models , compress and shear destroyed states , starting crack load and ultimate bearing capacity are obtained
• The near crack line analysis method is used to investigate an eccentric crack loaded by shear forces in a finite plate , and the analytical solution are obtained
• 2 . specimens ’ cracking loads under dead - load have been calculated based on the tension model of ordinary concrete . the calculating value is larger than the testing value by 29 % to 37 %
• Those include the load carrying capacity of the specimens in the limit state , the cracking load of the specimens , the crack width of the specimens and the deflection of the specimens
• Compared with the usual shear wall , shear wall with concealed steel bar truss have the following advantages : 1 . cracking load , yield load and ultimate load are obviously higher . 2
• Crack of column equal to improve rotating ability of end of beam . therefore , it improves ability of moment modulation of end of beam . 9 ) the secondary moment has important influence on crack load
• The result shows that the cracking load and the ultimate load are all increased to different extent , the rate of crack propagation has an obvious betterment and the seismic mechanism is also improved
• By low - cycle and reverse horizontal loading test , the properties of the walls such as the degree of the cracking load , yield load and failure load , the property of hystersis curves and keleton - frame curves and the property of ductility
• We made research on the degree of cracking load , yield load and failure load as well as die sequence of the structure crack and yield ; the internal force , the deformation , the failure mechanism of the building
• With the modeling method in this paper , it is showed that numerical load - displacement curves agree well with the experimental skeleton curves , and that the errors of crack load are bigger , but the cra
• In the elastic term , the two load - displacement curves slope are similar , the new structure s slope is more greatly . stiffness is better than the traditional structure . but the new joint s crack load is littleer
• And a nonlinear analysis of concrete beams on the basis of ansys program is used in order to overcome the shortcomings of experiments 。 the results indicate that locally strengthened technique has good reinforcing effect . it can improve the crack load , yield load and limiting load
• According to the cyclic reverse loading test of two brick masonry walls without reinforement and four pieces of brick masonry walls reinforced with afrp , the cracking load , the ultimate load , the ductility factor and the rate of crack propagation were compared each other
• This paper has put forward such one , i . e . to use the dimensional angle iron framework to strengthen the center of the knot in order to add its degree of toughness and stiffness , improve its crack load and aggrandize its ultimate deformation
• Through experiment this paper compares the crack load of concrete slab with liter polypropylene fiber and glass fiber , and compare with the numerical value of theory . in the calculation assume str ess figure of the extension area is triangle or rectangle
