[摘 要] 梯板平面內(nèi)橫梯方向的剛度及橫梯方向的地震分量對傳統(tǒng)樓梯的受力、安全都有著一定的影響。在鋼筋混凝土耐震樓梯設(shè)計(jì)中，可以在梯板的端部設(shè)置可滑動支撐面同時在側(cè)面設(shè)置緩沖構(gòu)造，用以消除橫向地震力破壞效應(yīng)。本文對國家新的樓梯設(shè)計(jì)標(biāo)準(zhǔn)詳圖提出了改進(jìn)意見。
[關(guān)鍵詞] 橫梯方向；耐震設(shè)計(jì)；緩沖構(gòu)造

Abstract: There must be some influence on the inner force and the safety of traditional stairs, by the cross planer rigidity of stair slabs and cross component of earthquake. In the shock-bearing design of reinforced concrete stairs, a buffer joint can be laid on the side of the stair slabs, coexisting with the slidable surface on a supported end, to eliminate the destroying effect from the cross component of earthquake. Some suggestions are given for the new standard drawing.
Keywords: cross direction; shock-bearing design; buffer joint
