ANALYSIS OF THE INTERNAL FORCE COEFFICIENT OF THE TRIMMER BEAM OF TWO-SPAN FRAME-SUPPORTED MULTI-RIBBED WALL BEAM

Considering the factors of span-to-span ratio of the wall beam,height-to-span ratio of the trimmer beam and height-to-span ratio of the wall,the orthogonal design of two-span frame-supported multi-ribbed wall beam is done and the internal forces of the trimmer beams are calculated with finite element method.Through the visual analysis and variance analysis of the results,the significance analysis of the factors influencing the internal force of the trimmer beam is done,and the influence of the opening position in the wall is also studied.Then,the internal force coefficient of the trimmer beam is obtained through regression analysis
