【单选题】下面关于配筋砖砌体的说法正确的是( )。
A.
轴向力的偏心距超过规定限值时，宜采用网状配筋砖砌体
B.
网状配筋砌体抗压强度较无筋砌体提高的主要原因是由于砌体中配有钢筋·钢筋的强度较高，可与砌体共同承担压力
C.
组合砖砌体在轴向压力下，钢筋混凝土面层与砌体共同承担轴向压力，并对砌体有横向约束作用
D.
网状配筋砖砌体的配筋率越大，砌体强度越高，应尽量增大配筋率

【多选题】关于台阶的说法正确的是?
A.
室外台阶的坡度比楼梯平缓，踏步尺寸一般为踏面宽 300~400  mm, 踏步高 100~150 mm
B.
台阶由踏步和平台组成，室外台阶有单面踏步、两面踏步等形式，有时也会和坡道一起组合，用于医院、旅馆、办公楼等建筑
