On pkpm of masonry structure. Beginners, please don't joke. Hmm. How interesting

1: It is very simple to form a PK file for the beam of masonry structure and calculate it in PK, or use the component calculation module GJ to calculate it, or calculate it manually. There are many small softwares that can calculate directly. It is a conceptual mistake to calculate with SATWE, although the beam reinforcement of the whole building can be obtained at once with SATWE.

2. Stair treads can be calculated by hand, or you can find a table to check. In fact, it is a simply supported beam inclined, but both ends of the stair tread inclined plate still have a certain consolidation effect with the concrete stair beam, so the mid-span bending distance can be calculated according to QL 2/ 10, and the bearing can take a certain bending distance. The reinforcement of the bearing generally takes 1/4 span.

3. Strengthen the details according to the tension in the bending distance diagram. If it is too complicated, it is necessary to analyze its stress. The tensile reinforcement can be calculated, and other structural matches meet the minimum reinforcement ratio. There is also a kind of structural reinforcement that is crack-resistant, but if it is too complicated, the construction will be difficult. It's best not to be too complicated. Some details are qualitatively analyzed according to experience.
