摘　　要：针对目前采用"打牮拨正"工艺解决西藏传统建筑梁柱歪闪问题在拨正后常出现重新歪闪的现象,以布达拉宫梁柱构件为例,通过轴心受压承载力的计算和考虑梁柱接头部位具有一定转动刚度的计算,提出增强梁柱节点刚度以提高柱子所能承受的极限压力的办法来解决西藏传统建筑梁柱歪闪的问题。“The housing is tilted, get it by pillars” was often used to solve the traditional architecture beam and column crooked problem in Tibet. But after the solution the crooked problem appeared again. Taking the beam and column member of Potala Palace as an example, the calculation of the axial compressive capacity was made by taking a certain rotational stiffness of beam column joints into consideration. Finally the conclusion is drawn that reinforced beam and column joint stiffness can enhance the ultimate pressure of the pillars to settle the Tibet traditional architecture beam and column crooked problem.
