按結構形式(shi)(shi)和受力特點樓梯形式(shi)(shi)可分為(wei)板式(shi)(shi)、梁式(shi)(shi)、懸(xuan)挑(剪刀)式(shi)(shi)和螺旋式(shi)(shi)，前(qian)兩種屬(shu)于平面(mian)受力體系，后兩種則為(wei)空間受力體系。
板(ban)(ban)式(shi)(shi)樓(lou)梯(ti)是由梯(ti)段板(ban)(ban)、平(ping)臺板(ban)(ban)和(he)平(ping)臺梁(liang)(liang)組成。梯(ti)段板(ban)(ban)是一(yi)塊帶踏步的斜板(ban)(ban)，斜板(ban)(ban)支承于上(shang)、下平(ping)臺梁(liang)(liang)上(shang)，底層下端支承在地壟(long)墻上(shang)。板(ban)(ban)式(shi)(shi)樓(lou)梯(ti)的優點是梯(ti)段板(ban)(ban)下表面(mian)平(ping)整，支模簡單;其缺點是梯(ti)段板(ban)(ban)跨度(du)較(jiao)(jiao)大時(shi)，斜板(ban)(ban)厚度(du)較(jiao)(jiao)大，結構材料用(yong)量較(jiao)(jiao)多。因此板(ban)(ban)式(shi)(shi)樓(lou)梯(ti)適用(yong)于可(ke)變荷載(zai)較(jiao)(jiao)小、梯(ti)段板(ban)(ban)跨度(du)一(yi)般不(bu)大于3m的情況。
