About how many steel bars are needed per square meter for brick-concrete structure.

30 ~ 40kg/m2, depending on the story height and seismic fortification requirements.

Code for Design of Masonry Structures is a technical legal document. Code for acceptance of masonry structures is a legal document of quality standards. It is impossible to list economic indicators in limited space. The content of steel bars per square meter is the economic reference data of design and construction in a certain period summarized through budget and settlement statistics. At present, the general situation of masonry structure is 30kg/㎡ (including general foundation).

Concrete and brick structure

It is a mixed structure, which is a mixed structural system composed of brick walls and reinforced concrete beam-column slabs. Suitable for small bay depth, small room area, multi-storey or low-rise buildings. The load-bearing wall of brick-concrete structure cannot be changed, but most of the walls of frame structure can be changed. Generally speaking, the service life and seismic grade of brick-concrete structures are low. Nowadays, brick-concrete structure has been changed into frame structure and reinforced concrete structure.
