Introduction

The purpose of the work is to develop practical skills for designing the simplest design elements by implementing the following system sequence:

assignment (adoption) of a general layout solution of the floor;

Select the design scheme of the element

load collection and determination of design forces;

selection of cross section according to the conditions of ensuring strength of the element at all design stages (manufacture, transportation and installation and operation);

Designing the element to meet the requirements of the design standards

checking the adequacy of the decisions made for compliance with the requirements of the second group of limit states;

graphic design of design results.

Monolithic ribbed floor

1.1 Initial data for calculation

It is required to design the slab and secondary beam of the monolithic ribbed beam floor at the initial data:

Zima construction area;

dimensions of the building temperature-and-transformation unit;

Floor payload

general design solution (bearing outer walls and inner frame).

pn - payload, kN/m2 = 5;

Rn, gr - standard soil resistance, MPa = 0.20;

L - building length, m = 72;

B is the width of the building, m = 20.6;

H - floor height, m = 3.9.
