software for designing structural elements of reinforced concrete.
With BETONexpress you can easily
design structural elements of reinforced concrete. For each structural
element, you specify the basic dimensions, loads and material properties,
and you obtain the detailed concrete design in ultimate limit state
(ULS), and in serviceability limit state (SLS).
The dimensioning is according to Eurocode 2, EN 1992-1-1:2004,
concrete structures, General rules and rules for buildings, with
supplement of Eurocode 7, EN 1997-1:2004, Geotechnical design – General
rules, for geotechnical analysis (footings, retaining walls), Eurocode
0, EN 1990:2002, for load combinations, and Eurocode 8 for seismic
loading. The last EN versions of the Eurocodes are implemented.
You can also compute the capacity of slabs, beams and columns strengthened
with FRP (fibre-reinforced polymers). Regular and light weight aggregate
The program's CAD modulus automatic generates detailed drawings of the
structure and the reinforcement. A combined detailed report and
reinforcing steel schedule is produced for the designed concrete
components. Assumptions and references to design codes are shown in the
report. The reinforcing steel schedule can be edited with a specialised
editor which is included. The user can select the applicable National
Annex. The design code parameters, as well as default values, can be
adjusted by the user. Design Charts and Tables for use and understanding
of Eurocode 2 are included n the program. In addition a set of
engineering tools are included in the program.

Soil bearing resistance
Drained and undrained conditions
The basis for the design of foundations is
the bearing resistance of the soil.
The design bearing resistance can be calculated using analytical or
semi-empirical methods. Annex D of Eurocode 7, EN1997:2004 describes a
method of obtaining the design bearing strength of the soil.

Fundaments of Steel columns
The concrete footing of steel structures
has to be designed to resist soil pressure for maximum vertical load and
it must have enough weight to resist uplift from wind or seismic
You can design Pin and Fixed end column foundations.
You can also specify if the foundation has a horizontal tie to take the
horizontal outwards forces or not.

Steel Tie and Passive earth
The high horizontal forces acting at the
base are acting outwards as a result of bending in the columns due
to vertical loading on the roof. This is resisted in two ways.

Earthquake analysis according to Eurocode 8 (EC8), Mononobe-Okabe.
Two different types of cantilever walls in the program:
- Type-A. Walls with very small back heel. The
active earth pressure is computed using Coulomb's theory at the back face of the wall.
- Type B. Walls with back heel. The active earth
pressure is computed using Rankine's theory at a vertical surface at the end of the heel.
The design of cantilever type walls is based
on Ultimate Limit State Design of concrete according to Eurocode 2. The design checks are
performed at each tenth of the stem height. The reinforcement of the stem is optimised,
and depending on the stem height the reinforcement is reduced toward the top of the wall.
The reinforcing bars are automatically placed in the reinforcing bar schedules. Optional

Water basins, swimming pools
Design of rectangular water basins.
The solution is for a 2-dimensional cross section across the
smallest dimension (width) of the basin.
The basin is assumed to sit on elastic
ground and is analyzed with finite element analysis. The basin walls
are subdivided in 2 beam elements of length H/2.
floor is modelled with 16 beam elements with nodal points connected
to the ground with elastic springs. The
stiffness of the elastic springs is computed from the Winkler’s
foundation modulus Ks [kN/m2/m].
The loading conditions include all the load cases according to
Eurocode 0 (EQU, STR and GEO) for:
· Empty water basin (only earth pressure)
· Filled water basin without earth pressure
· Filled water basin with earth pressure
The reinforced concrete
design includes also serviceability control with limit crack width
specified by the user.
Basement walls (2015)
Walls with only the bottom restrained for lateral
Walls with restrained the bottom and the top for lateral movement.
In the first case the sliding of the wall is prevented due to
the retraining of the base in movement. The active earth pressure is
computed as usual using Coulomb’s (1776) or Rankine’s (1857) theory,

In the second case, the active earth pressure conditions are
