Essay On Brick Masonry

Brick masonry is an earliest building technique, and masonry constructions constitute a large share of structures around the world. Such structures are required to withstand extraordinary dynamic loading caused due to accidental impact or seismic activity, along with this brick masonry is a composite material made of brick units which are usually made from clay and mortar. Masonry is in general a highly resilient type of construction. However, the materials that are used, quality of the mortar and workmanship and the arrangement of the unit can considerably affect the durability of the whole masonry construction.

There are many variables that affect the mechanical behavior of brick masonry such as the brick and mortar properties, brick geometry,

• The development of adequate stress analyses for brick masonry.

• To develop a deeper understanding of the behavior of brick masonry based on experiments and computer methods.

• To fulfill the above aim the material characterization of brick masonry is carried out through experiments performed in material testing laboratory.

1.2 SCOPE OF WORK

Goals of the project:

The goal of this project is to do macro computer modeling of brick masonry under seismic loading in order to convert the highly indeterminate and nonlinear behavior of brick masonry into something that can be understood with an acceptable degree of certainty and in order to define and describe the behavior of masonry under seismic loading.

Deliverables:

• Extraction of mechanical properties of unreinforced brick masonry.

• Development of macro computer model on SAP under seismic load.

Limits and exclusions:

• Mechanical properties of only unreinforced poor quality brick masonry are extracted.

• For computer modeling SAP 2000 is used and macro modeling technique is adopted.

• In extraction of mechanical properties of brick masonry ASTM standards are followed.
