1.- ALCANCE.

Se tiene planeado construir un edifico que tendr la funcin de Punto de venta, adems de contar con un rea de atencin y baos.

El edificio ser de un piso.

La presente memoria revisara la cimentacin las columnas y techo para las distintas cargas a las que ser sometida la estructura, como cargas propias, cargas vivas, sismo, viento, cabe comentar que se realiz un estudio de mecnica de suelos, en donde nos indica que tipo de cimentacin recomendada.

2.- REGLAMENTOS PARA ANALISIS Y DISEO. Manual de obras civiles, (CFE). ACI-08, American concrete institute. AISC-10 LRFD, American Institute Steel Construction, por factores de carga. Normas Tcnicas Complementarias 2004 sobre criterios y acciones para el diseo estructural de las edificaciones. (NTCCA-RCDF-2004)

Para el anlisis y diseo de la estructura se emple el software, Ram Elements 10.53.- PARAMETROS DE DISEO.

LOCALIZACION:

La localizacin geogrfica del sitio de estudio se estableci empleando un Sistema dePosicionamiento Global (GPS). Con ello se determin que las coordenadas UTM mediascoincidentes con la posicin del predio corresponden, a las 795005 y 2121888 del Huso14Q.El sitio destinado para el proyecto corresponde al Macrolote 11, con rea cercana a las 12hectreas, ubicado hacia el costado poniente de la zona denominada Centro Comercialdespus del Macrolote 12, as mismo se encuentra ubicado entre las dos vas de ferrocarril

Uso: Comercial

Clasificacin de la estructura segn su importancia: Grupo B.

Factor de comportamiento ssmico: Qx=Qy= 2 Capacidad de carga del terreno: 20 tons/m2

Espectro de Diseo Ssmico:Del estudio de mecnica de suelos:

Del programa prodisis de CFE, tenemos el coeficiente ssmico para el mtodo simplificado.El coeficiente ssmico es de 0.36

Verificacin de requisitos de CFE, para validar que la estructura puede ser revisada con el mtodo de diseo ssmico simplificado del manual CFE:4.- MATERIALES

Notes

* Torsion is not considered for design.

* Only columns with rectangular or circular sections are designed.

* Each column is verified considering only the forces at the ends of the member.

* The transverse reinforcement is ordered from bottom to top of the column.

* Ve = Design shear force from member moment capacity (2Mp/L). The contribution of the applied gravity shear force is not considered.

* Required So = Maximum spacing between stirrups considering special or intermediate moment frames in the distanced covered by (Lo).

* Calculated Lo = Minimum calculated length measured from joint face along axis of the member, over which transverse reinforcement must be provided with a spacing So. This length is only required for intermediate and special moment frames. ACI 318-11 21.6.4.1

* Lu = Unsupported length.

* K = Effective length factor.

* Cm = A factor relating actual moment diagram to an equivalent uniform moment diagram.

* Sway = True if column is considered unbraced in its local axis.

* Mc = Factored moment to be used for design. Considers the slenderness effects of the column. Mc = Mu*ns.

* n2 = Amplification factor to account for small P-delta effects (P-).

* Mn = Nominal moment strength.

* Mc/(*Mn) = Strength ratio. The bar graphs indicate the relative ratio of Mc/(*Mn) for each load condition. If a bar is shown in red the ratio is greater than one.

Notes* Only the design bending forces (Mu), shear forces (Vu) and torsion moments (Tu) are considered in the design.* Values shown in red are not in compliance with a provision of the code* The positive and negative flexural reinforcement includes the longitudinal reinforcement required to resist torsion. Refer to the note below on the VCT column to determine when torsion and compression bars are provided. The longitudinal reinforcement area considers the minimum area required by Code (10.5).* When the moments diagram increases in the same direction of the development length of the bars, the bars will not contribute to the member strength for a Code specified distance equal to max(12*db,d).* If the section at which member flexural strength is being calculated is within the development length of a group of bars, the bars will contribute to the bending capacity an amount proportional to their actual length / their full development length.* The transverse reinforcement is ordered from left to right.* The program does not consider ACI318-11 section 12.11.3 whereby the bar diameter is limited according to the location of the bar cut-off.* Asprov is the provided reinforcement, considering the reduction due to the development length as described previously.* "C" shows the span critical station.* Ld,Ldh = Development length of each bar. If the bar ends with a hook, it considers the Ldh length.* Splice lengths shown are not reduced by the factor Asreq/Asprov.* sb = Free distance between top or bottom bars corresponding to the layer closest to the extreme face of the beam (layer1). It is not calculated when there is only one bar.* Stirrups VCT = Flag that determines if stirrups are required to resist shear forces (V), torsion (T) or to confine the the longitudinal compression bars from buckling (C).* Closed = Flag that indicates if the stirrups are closed (yes) or open (no).* Mu/(*Mn) = Critical strength ratio for the station. If the value is in red, it is larger than 1.0* Al = Total additional longitudinal reinforcement required by torsion.* Spa = stirrup spacing provided by the user.* Spa lim = spacing limits due to geometry.

Analysis result

Plate reinforced concrete design in local axesDesign code: ACI 318-2011Notes:- Membrane forces are ignored in the design- "Bot" is the bottom edge of the plate (-t/2)- "Top" is the top edge of the plate (+t/2)- "ec" is the controlling load condition- Face +t/2 is in compression if bending moments are positive- Large rebar areas (in the order of 1E300) indicate an error in the design due to insufficient thickness of the shell or insufficient strength of the material

Notes

* Soil under the footing is considered elastic and homogeneous. A linear soil pressure variation is assumed.

* The required flexural reinforcement considers at least the minimum reinforcement

* The design bending moment is calculated at the critical sections located at the support faces

* Only rectangular footings with uniform sections and rectangular columns are considered.

* The nominal shear strength is calculated in critical sections located at a distance d from the support face

* The punching shear strength is calculated in a perimetral section located at a distance d/2 from the support faces

* Transverse reinforcement is not considered in footings

* Values shown in red are not in compliance with a provision of the code

*qprom = Mean compression pressure on soil.

*qmax = Maximum compression pressure on soil.

*max = maximum total settlement (considering an elastic soil modeled by the subgrade reaction modulus).

* Mn = Nominal moment strength.

* Mu/(*Mn) = Strength ratio.

* Vn = Nominal shear or punchure force (for footings Vn=Vc).

* Vu/(*Vn) = Shear or punching shear strength ratio.
