General
Masonry buildings are oldest and traditional building types. Because of vertical loads and horizontal loads such as earthquake transported by walls masonry buildings quite economical compared to concrete and steel buildings. Masonry elements are less ductile than steel or concrete elements so their seismic energy absorption capacity is lower. For example , seismic forces can be reduced with R=8 coefficient , but Project made with high ductility level can act like building with normal ductility level ( R=4) due to mergence and application errors. And that’s makes building designed with 100 ton horizontal force to get 200 tons load. Masonry buildings earthquake force reduced by a R=2 factor. The ductility and strength of building can be increased with vertical bond beams in the buildings corner or wall intersections.
Masonry buildings are very sensitive to seismic forces , because of that wall elements with high or low seismic ( shear) strength aganist the effects of vertical load , wall neighboring windows with low height which cause short colomn effect makes them get a lot of seismic force which requires unique calculations.Modeling done with StatiCAD-Masonry also have buildings static calculations according to earthquake regulations with slab calculations, which make sure building also resistance aganist earthquake. Buildings with insufficient components shown in graphical interface with different color according to failure status..
Horizontal bond beams and loads transfer from upper floors to lower floor walls done in sensetive manner. Seismic loads which effects floors automatically determined according to building floor weight. Shear stress safety calculated separately for each wall depending on the vertical load.
Loads are transferred from walls to foundation and foundation ground safety and foundation section capacity will be verified and reported.
Program can prepare project drawings and project cover together in one step.
Building can be strengthened with steel mesh and shotcrete. Program calculates static reinforcement requirements for steel mesh.
Masonry buildings need all the calculations and verifications that prescribed in seismic regulations to be resistant to earthquakes. StatiCAD-Masonry automatically calculates all the necessary verifications in a very detailed way. 7
COMPARISON OF MASONRY BUILDINGS WHICH CALCULATED WITH ONLY SLAB AND MASONRY BUILDINGS CALCUTED WITH STATI-CAD YIĞMA
Advantages of StatiCAD-Masonry to other Static Programs
1)Static analysis made with resemblance of concrete panel/curtain/ high beam is different than calculations presribed in earthquake regulations. StatiCAD-Masonry is a specialized program for masonry buildings and because of that it’s fully complliant to the earthquake regulations.
2)In the analysis performed for masonry buildings with reinforced concrete analogies , account reports shows that it’s lack most of the described parameters in earthquake regulations. Almost every step of the calculation made by the StatiCAD-Masonry can be seen from the reports.
3)The materials described in the earthquake regulations for walls can be changed by selecting ‘’ create/change wall’’ options. That options allows user to change wall density, allowable crack stress , compression safety stress etc. Also wall’s compression safety values taken from table which makes users free from trouble.
4) Program can prepare project drawings and project cover together in one step.
5)It is very easy to model with StatiCAD-Masonry.
Basic Features of StatiCAD-Masonry
Easy to use and advanced graphics interface.Overall structure analysis in one step and side by side Project drawnings witn one touch Structures with half basement / stepped buildings?? Calculations Optionally , vertical bond beams can be considered as contributors to the seismic behavior of the building
strengthened and unstrengthened calculation reports and performance reports can be made with a single Project file.
strengthened jackets can contribute to the wall compression capacity Determine specifid stiffness coeffcient for walls Load factors can be changed manually for compressive stress controls and shear stress controls.
Instead of establishing reinforced concrete analogies , StatiCad-Masonry uses earthquake regulations.
Precisely determining vertical wall loads with ‘yield line theory‘’ in vertical load analysis. Compression and shear stress safety controls for the walls.
Different material properties can be entered for each wall , values can be taken automaticly from seismic regulations or, experimental values can be entered. strengthening jacket reinforcement calculation strengthening drawing ( steel mesh, jacket drawning and anchor details in the wall section) With an advanced drawn editor like AutoCAD , you can edit the drawings and make them dwg without any loss.
Capable of giving offset value to the elements.
