This document discusses various structural systems and design considerations for high-rise buildings. It covers core types and placements, structural systems like diagrid, tube structures and load-bearing walls. It also discusses services like parking layouts, elevator types and criteria, mechanical systems, and considerations for wind loads and natural ventilation challenges in tall buildings.

Diagrid (a portmanteau of diagonal grid) is a
design for constructing large buildings
with steel that creates triangular structures with
diagonal support beams. It requires
less structural steel than a conventional steel
frame.
A load-bearing wall (or bearing wall) is
a wall that bears a load resting upon it by
conducting its weight to a foundation structure.
The materials most often used to construct load-
bearing walls in large buildings are concrete,
block, or brick.
Concept
The tube system concept is based on the idea that a building can be designed to resist lateral
loads by designing it as a hollow cantilever perpendicular to the ground. In the simplest
incarnation of the tube, the perimeter of the exterior consists of closely spaced columns that
are tied together with deep spandrel beams through moment connections. This assembly of
columns and beams forms a rigid frame that amounts to a dense and strong structural wall
along the exterior of the building.

Elevation, structural position ,size:
5. Large lateral drift from a certain height.
4. Strength and rigidity depend on individual column and beam.
2. Vertical plans: columns and girders.
3. Horizontal plans : beams and girders.
6. Core contains mechanical and vertical transportation system.
1.Rigid joints between vertical and horizontal plans.
1. No deep beam, allowing minimum story height
1.Large amount of steel is required.
Suspension :
1.Cables carry the gravity loads to truss.
2. Cantilevering from a central core.

PARKING:
There are two types of car parking systems:
*A parking lot (British English: car park), also known as a car lot, is a
cleared area that is intended for parking vehicles. Usually, the term refers
to a dedicated area that has been provided with a durable or semi-
durable surface.
*Automated car parking system is a mechanical device that multiplies
parking capacity inside a parking lot. Parking systems are generally
powered by electric motors or hydraulic pumps that move vehicles into a
storage position.
***The standard calls for angle of departure is minimum of 10
The maximum ramp slope should be 20%.
RAMP
At 1 : 8 ratio, ramp
will starts minimum
3 meters or 10 ft
distance from road.
12. Parallel straight-ramp system withramp- wells on two structure sides.
Straight-ramp system with one ramp-well.
60° parking.
90° parking.
45° parking.

15. 1.Traction elevators
2. Hydraulic elevators
There are three types of elevators
3. Climbing elevator.
Climbing elevator – They hold their own power device on them,
mostly electric or combustion engine. Climbing elevators are often
used in work and construction areas.
Two common performance criteria for elevator design:
the average waiting interval --- 30 sec. 5 min. holding capacity --- 13%.

16. In high-rise buildings generally We cant permit the natural air
Entrance due to the lateral pressureOf wind.
So we don’t use operable Glass.
Wind Flow
standardspage no-15
17. GUST VELOCITY
The dynamic gust velocities produce dynamic wind pressure that
create additional displacement of the building for slender buildings the
may become dominant-
If a building and its foundation were rigid, it would have same
acceleration as the ground, that is by newton's law - F=MA
