The document provides a structural calculation report for a residential home designed by Prefabricados y Modulares de Monterrey. It describes the prefabricated walls, slabs, and foundation slabs that make up the structure. The structural elements were modeled and analyzed using SAP2000 software. Load combinations were considered according to design guidelines. Reinforcing steel requirements were calculated for structural elements based on moment and shear demands from the analysis.

Out of Plane Behavior of Contained Masonry Infilled Frames Subjected to Seism...paperpublications3
Abstract: Brick masonry infill although considered as non-structural element largely affects the strength, stiffness and ductility of the reinforced concrete frames during the application of lateral loads due to wind or earthquake. Contained masonry refers here to the brick masonry which is used as infill in a reinforced concrete frame, wound round with 8mm diameter mild steel wires in vertical and horizontal directions and stitched to the brick masonry as well as to the reinforced concrete frames. This thesis focuses on the seismic behaviour of reinforced concrete structures with contained masonry infill, with a particular interest in the development of rational procedures for the analysis and design of RC frames with contained masonry infill. The estimation of the natural frequencies of the structural system is the basic investigation in dynamic analysis of a structure. Therefore the analysis is primarily to find out the modal frequencies of the structure and to simulate the mathematical model to earthquake loads. The structure vibrates in different modes when the earthquake takes place. The methodology suggested is to carry out a detailed study on the influence of contained masonry infill including un-reinforced masonry infill in multi-storey Reinforced Concrete frames on the fundamental natural frequencies and response due to various earthquake excitation forces. Numerical Finite element analysis is carried out on two dimensional Reinforced Concrete Frames under different configurations of contained masonry infill in addition to plain masonry and bare frames. The RC frames were designed and detailed as per relevant Indian standard codes. The present work consists of study of the behaviour of five storeyed RC frames infilled with contained masonry and also infilled with plain masonry, subjected to various earthquake excitation forces. Three types of models are considered for analysis; five storey frames of 4m wide, 5m wide and 6m wide models having total height of 16m with plain masonry infill and contained masonry infill are considered.

home is provided by Prefabicados y Modulares de Monterry, S de R.L. DE C.
V.
For the design of this structure the following design guidelines were
considered, in accordance to the plans provided by PyMM.
1 Solid Walls and Slabs of Lightweight Concrete
2 Load Bearing Walls
3 Foundation Slabs
4 Live load of Roof of 170 kg/m2
5 Additional Dead Load of Slab of 170 kg/m2
This report is presented in a descriptive format, giving special emphasis in
describing the criteria of analysis and the designs utilized in this structure.
A annex to the main body of the report is also presented, where the results
of the computer simulations are itemized for the structural design.
2 Description of the Structure
The structuring of the home consists of prefabricated walls and slabs (figure
1), Foundation slabs. (Figure 2), Walls, slabs and Foundation Slabs are
assembled, (Figure 3), Facades (Figure 4) and a spare room can be attached on
site with solid concrete walls and slabs (Figure 5) The walls and the slab are
cast monolithicly with lightweight concrete, the foundation slab is cast
with high strength concrete and the facades are cast with lightweight
concrete.
Once cast the components are connected to form a house.

3. 3 Dimensional View of the Slabs and Walls
3 Dimensional view of the Slab and Walls. The slab and walls are
cast monolithically with concrete with the density of 1.400kg/m3,
and with the Strength of 130kg/cm2 with a thickness of 12cm, the
walls were articulated at the bottom where it connects to the
foundation slab.

5. 3 Dimensional View of the Assembly
The assembly for the walls, slab and foundation slab is modeled
in what is considered in its final state, when they are assembled on
site in the model they are supported on springs whose stiffeness is
similar to the final terrain. Attached to the foundation slab.
6. 3 Dimensional View of the Facades
The Facades are simply modeled supported on the connection
points where they are attached to the wall plates of the home,
cellular concrete was used with a density of l.400/m3
7. 3. Design Criteria
For the final dimensioning of the structural elements the guidelines set by
PyMM were taken into account for the design. The criteria used in the design
are:
a) The elements of the concrete ; were carried out following the
recommendations of ACI-318-05, ACI-523.2R-96 Y ACI-213R-99
b) High strength concrete was considered with the compression strength
of 300 kg/cm2, 150 kg//cm2 and for the cellular concrete of 130kg/cm2.
c) Reinforcement steel of 4200kg/cm2 was considered.
4. Estimation of design loads and combinations
Presented below to calculate the loads considered for the design of the
structure and foundation, as well as combination of loads used in the
structural analysis.
4.1 Dead Load
It is considered the as the weight of the main structure, concrete plate, clay
block, reinforcement steel and others.
Following way:
Concept Weight (Kg/m2)
Weight of the plate (cellular concrete) 175
Weight of the plate (high strength concrete) 300
Additional Dead Load
Weight of tile and mortar 55
Weight of dividing walls 100
Weight of finishing 15
8. 4.2 Live Load
A mezzanine of three walls is considered a live load.
Live Load of 170 kg/m2
4.3 Design Combinations
Several combinations of loads were considered in the designing of the struct-
-ural elements. The basic loads used and combinations for the main structure
were included in the analysis, while the loads used for the foundations were done
separately, both combinations are shown together.
