Research Of Calculative Method To Balcony With Side Beam

In industry and civil construction, stemming from need of function and spatial sculpt. When balcony designed. We often uses balcony with side beam .Because of existence of side beam causes the mutual restraint function to strengthen. Make the structure to be reasonable . At current design criterion, have no method of balcony of structure components. Usually when the designers process the designing of balcony ,they have no thinking of harmonious action of components which are side beam and shoulder beams. In which the important place, what is the deflection of shoulder beams which comprise side shoulder beams and middle shoulder beam, taken out of account .Because force to middle shoulder beam is bigger than force to side shoulder beams. The deflection of middle shoulder beam is bigger than side shoulder beams. The out of harmonious action will cause change of internal force to side beam. then the internal force to shoulder beams also changed .How many of the change ?The paper give the right reply through the research of influence of internal force that deflection of shoulder beam cause. Moreover ,the paper give the calculative method under the condition of deflection of shoulder beam.In front of research ,the paper do some research to calculative method of shoulder beams which include equal section and no equal section shoulder beams. When the paper done the paper adopts finite element software SAP2000. The operation of SAP2000 is simple , The result of calculation is more exact than other finite element software. So the result of model is exact.Moreover, In the middle of the system of balcony with side beam ,side beam and shoulder beams a crossed. The accosted node is different with node of beam and pole. The pole is impending. So the mutual action is different with action of beam and pole. If we separate the side beam and shoulder beam ,then we get the result which is not agree with the fact .For find out the problem, the paper think of the mutual action of side beam and shoulder beam, Do some important research ,Analysis the capability of node .elicit the formula of calculation to internal force. The formula is applied to designers. They can obtain the result of internal force under the condition of mutual action easily.The paper obtain more right calculative method , The result of the method is exacter than...
