APM Civil Engineering

APM Civil Engineering — modern CAD/CAE system for automated design of construction facilities for civil and industrial purposes; it is developed in the context of the latest achievements in the field of numerical techniques, computational mathematics, programming and also theoretical and experimental engineering solutions.

Steel Construction Design

APM Civil Engineering system helps to:

fully or partially create the metric model of a steel construction using libraries of mostly developed standard layouts;

check bearing capacity and automatically select the best cross-section of rod (based on strength and stability criteria and in compliance with Construction Rules 16.13330.2011) from the library of standards cross-sections or a user prepared library;

analyze strain-stress distribution of a steel construction;

automatically get drawings of standard nodes and joints of steel constructions;

calculate welding joints of node elements and group bolt joints;

prepare projection drawings of a structural model in whole and its

separate elements;

get a consumption table for steel construction elements.

Concrete Structure Design

Concrete structure design tools of APM Civil Engineering help to:

present concrete construction models as combinations of elements of columns,

collars, beams, overlaps, slabs and covers;

calculate design combinations of forces (RSU);

analyze strain-stress distribution of a construction;

select reinforcing of concrete components (square, T-shaped, I-shaped, round and circular) in compliance with Construction Rules 52-101-2003 for the first and second groups of limit states for the most dangerous combination of internal forces to the construction elements;

make design and checking calculation of concrete components;

make calculation of foundations including definition of geometrical dimensions, settlement of ground under the foundation and selection of reinforcement

(in compliance with Construction Rules 50-101-2004);

get a convenient form to submit calculation results including the real picture of fitting placement within a reinforced concrete element.

Reinforced Masonry Structure Design

APM Civil Engineering helps to calculate masonry and reinforced masonry structures. Such structures include construction facilities with such elements as brickwork, block work, etc. Rock material (ceramic and sand-lime bricks, cement blocks, brick and building tile blocks, etc.) are normally used in low-rise construction for walls or other parts of concrete, metal and wood buildings. Calculation of reinforced masonry structures in APM Civil Engineering are made in compliance with Construction Rules 15.13330.2012 and amount to checking calculation. If calculated strength characteristics are not satisfactory, a designer has to make constructive reinforcement and repeat the calculations. If necessary, this operation can be repeated until the required result is obtained.

Wooden Structure Design

Wooden structure calculations in APM Civil Engineering are distinguished by the following:

during design of construction wooden facilities it is possible to use standards schemes available in APM Civil Engineering;

strength calculation of wooden structures is made by the finite element method and in compliance with Construction Rules 36554501-002-2006 (TSNNISK standard);

it is possible to automatically select metal toothed plates and dowel joints;

it is possible to print drawings of all construction elements with cutting parameters.
