The corner windows open houses have beautiful appearance,better visual effect,good ventilation and lighting conditions,etc.,to get more and more applications in practical engineering.However,due to the design of architectural shapes and three-dimensional flat space complex irregular shape,could easily lead to damage during an earthquake.This is because the corner parts of the open windows will greatly weakened after a corner window at the corner shear connection,allowing members under seismic torsion force more complex near the corner of seismic more negative.There are no existing design specifications on the corner window design method,the designer for this set of high-rise residential corner window shear wall structure to a large extent by conservative methods for calculation.In construction,the general lack of control on the stress thinking and analysis of construction technical staff.Often on the structural requirements reinforcement reach reasonable request.A lot of people right corner windows open question no in-depth study of the basic concepts confusing.Therefore,the angle of shear wall structure on the local stress window settings influence and strengthen systematic research methods to identify the location and size range of impact angles window opened on the structural stresses and summarizes reasonable and effective control measures is an urgent need to strengthen.In this paper,based on finite element software,the finite element model of high rise window corner,the structure is applied to the seismic effect on the wall,floor,bended beam study the force.By modal response spectrum analysis,the displacement angle of the member,the corner;through modal analysis,the natural frequencies and mode shapes structure;through dynamic analysis,corner members get stress,internal force,analyze get corner window size and strengthen measures on the structure.First,through the analysis of simulation examples,details the process of applying finite element software to high rise window corner seismic response analysis,and based on the results of modal analysis,drawn up no floor corner window and landed on the corner of the window impact of third-order frequency front structure,the structure of reversing the impact of irregular;modal response spectrum analysis based on decomposition,come to strengthen measures on bended beam deformation;Finally,the model dynamic analysis,summed up the corner post,with the corner window size increases impact on corner members torsional stress,and by analyzing the measures taken to strengthen the structure after study adds angle plate thickness,while adding additional beams and oblique angle plate thickness and the addition of three inclined beams strengthened which measures more effective.Making conclusions on the specific design and construction work has played parts of reference.
