Masonry wall construction

Masonry walls of various sorts are utilized in building construction. Masonry walls are the most enduring feature of any structure or building. It separates a structure from the outside world. In masonry construction, the common masonry materials used are building stone, brick, cast stone, glass block, and concrete block. Masonry construction is a type of construction that has the highest durability.

12.7 The lateral force that is generated during building shaking can be calculated with the equation: Force = mass x acceleration, Based on this, which one of the following statement(s) is correct? ⚫ A building's total seismic design force is proportional to its weight. ⚫ Seismic forces are applied at the ground level; therefore, a building's upper floors have very small seismic force. ⚫ The largest seismic force is generated at the upper floors where they have the highest acceleration. . Seismic protective devises that dampen (reduce) building acceleration may be used to reduce the building seismic force. 12.8 Given five-story building, that weighs a 100kips and has concrete shear walls and special moment-resisting frames: a) Determine Response Modification Factor, R, from ASCE 7, Table 12.2-1 for Dual System of Special Moment Frame and Special reinforced concrete shear wall (Type D-3) b) Calculate Seismic Base Shear (V) using the following ASCE 7 equations and building information:…
