Reinforced concrete columns and beams are important structural elements that carry compressive and bending loads respectively. Columns can be categorized as short or long based on their height-width ratio and as spiral or tied columns based on their shape. Beams are classified based on their supports as simply supported, fixed, continuous, or cantilever beams. The construction of RCC columns and beams involves laying reinforcement, forming the structure, and pouring concrete to create these load-bearing elements.
This document discusses beams supported on an elastic foundation. It begins by introducing the Winkler foundation model and defining short, medium, and long beams based on the parameter βL. It then provides solutions for the deflection, slope, bending moment and shear force of an infinite beam under a point load. The document also discusses beams supported by discrete elastic supports and beams subjected to a distributed load segment. It provides examples calculating deflection, bending stress, and pressure for specific beam problems.

Formwork is used to shape and support concrete until it gains strength. It can be made from various materials like timber, plywood, steel, aluminum, and plastics. Timber was traditionally most common but other materials are increasingly used. Different types of formwork exist for walls, slabs, columns, etc. Proper formwork construction involves propping, shuttering, providing chambers, cleaning, and surface treatment. Formwork must be removed carefully in the proper sequence once the concrete has gained enough strength. The type of material used depends on factors like cost, availability, and need for reuse.

Analysis and comparison of High rise building with lateral load resisting sys...DP NITHIN
Emporis standards define a high rise building as “A multi-storey structure between 35-100 meters tall”. When buildings become taller and taller, the effect of lateral load on the structure comes into existence. The lateral action on the structure is majorly induced by the wind and seismic force.
They needs a lateral load resisting system to maintain the structure stable when lateral loads are applied to them.
The different lateral load resisting systems in the high rise building are
Moment Resisting Frame(MRF), Shear wall system, Bracing system

Projek Cekap (M) Sdn. Bhd. has provided spun pile foundation services for construction projects in Malaysia since its incorporation. They install pretensioned spun concrete piles, which transfer structural loads through the ground to stable soil or bedrock. The piling process involves assembling a circular steel reinforcement cage, placing it in a cylindrical mold, pumping concrete into the mold, spinning and curing the concrete, then transporting and installing the finished pile using machinery. Spun piles can be easily joined as needed for depth and provide a stable foundation even in loose soils or sloping areas.
The document discusses stress ribbon bridges. It begins by explaining that a stress ribbon bridge is a tension structure similar to a suspension bridge, with suspension cables embedded in the deck which follows a catenary arc. Unlike simple suspension bridges, the ribbon is stressed in compression which adds stiffness. Supports provide upward thrusting arcs to change the grade between spans. Stress ribbon bridges are typically reinforced concrete with steel tensioning cables to prevent excessive flexing from vehicle traffic. Fewer than 50 have been built worldwide due to their rare design.
A continuous beam has more than one span carried by multiple supports. It is commonly used in bridge construction since simple beams cannot support large spans without requiring greater strength and stiffness. Continuous prestressed concrete beams provide adequate strength and stiffness while allowing for redistribution of moments, resulting in higher load capacity, reduced deflections, and more evenly distributed bending moments compared to equivalent simple beams. Analysis of continuous beams requires determining primary moments from prestressing, secondary moments induced by support reactions, and the combined resultant moments.

4. REQUIREMENTS
Site Preparation and Excavation
• Excavate and level the area per engineer’s drawings. Refer to plan view and cross-section details
and excavate bed to accommodate chambers and manifold system. Be sure to allow for a mini-
mum twelve-inch (305 mm) stone border around the perimeter of the system and unforeseen
overages in your excavation calculations.
• Remove any standing water and maintain positive drainage of the site throughout the installa-
tion. Dewatering procedures must be used if necessary.
• Prepare the sub-grade soil for the chamber bed as specified by the engineer’s drawings.
• Place CULTEC No. 410™ non-woven filter fabric (or equivalent — see Table 6, page 15) on the
excavated bed bottom and perimeter sidewalls as specified by the engineer’s drawings. Filter
fabric is required on the sides and over the top of the system. It is also recommended on the
system bottom. Overlap the filter fabric by at least 24 inches (610
mm) where the fabric edges meet.
• Disperse a level base of 1 to 2 inch diameter washed, crushed
stone over the entire area of the bed bottom (see Table 4, page 14
for stone requirements). Refer to the engineer’s drawings for sub-
grade soil preparation and required stone foundation thickness.
• Using a vibratory roller, compact the stone with full dynamic force
applied to achieve a flat surface.
Chamber Preparation and Installation
CULTEC Contactor® and Recharger® chambers have the distinctive features of a fully formed end wall
and over-lapping rib connection.
CULTEC chamber ribs are dimensionally sized with an open large rib and a closed smaller rib to allow
for an easy interlocking rib connection.
CULTEC chambers are typically installed in a series of one or more chamber rows.
• Place one Starter Unit (Model S for Recharger® series, Model R for Contactor® series) as designed
for each row of units to be installed.
• If using side portal internal manifold, trim side portal according to guidelines located on sidewall
of the chamber, as required. Place trimmed portals over one rib of each Feed Connector to be
connected. Refer to Manifold Installation section on page 9.
• Place middle chamber (Model I for Recharger® series, Model E for Contactor® series) so the di-
rectional arrow located in the center of the units points downstream towards the end of the line.
Overlap the large open end rib over the small rib of the preceding chamber’s end wall, interlocking
the chambers together. When placing chambers take care to maintain center-to-center separa-
tion requirements, measuring from the base of the chamber.
• To ease backfilling requirements, only install as many middle
chambers as the stone-laying bucket or conveyor can reach.
• Place stone as outlined on pages 10 - 11 taking care not to drop
stone over the last rib to be overlapped.
• Continue chamber and stone placement using middle chambers
(Model I for Recharger® series, Model E for Contactor® series), until
the last unit in the row is to be placed, at which point the Model E
chamber is used to end the line.
Prior to the placement of the next line of chambers, the level and alignment of the chamber units shall be checked and cor-
rected, where needed.

Manifold Installation
• Utilize the side portals located on the chamber as an internal manifold in locations where indi-
cated on the engineer drawings. HVLV™ Feed Connectors are inserted into the portals to promote
flow. An additional external manifold is not required. CULTEC No. 20L™ Polyethylene Liner is to
be placed under the chambers utilizing the internal manifold feature and in locations where flow
rates may be increased per engineer’s drawings.
• Most installations are designed with the internal manifold located at the ends of the chamber
bed. However, the side portal internal manifold feature allows for the manifold to be located at
any point within the chamber run. Refer to system design for manifold location(s). Install cham-
bers according to directional arrows located in the top center of the unit.
• Using a reciprocating saw or router, trim the sidewall portals of the units that are to receive the
HVLV™ Feed Connectors. Feed connectors may be placed on any chamber requiring a manifold,
as indicated by the engineer’s drawings.
• Place the HVLV™ Feed Connectors into the side portal of the chambers per engineer’s drawings.
• Check for correct center-to-center spacing of chamber runs ac-
cording to engineer’s drawings before proceeding to next row.
• Insert in-flow pipe(s) into endwall or side portal as detailed on
engineer’s drawings. See page 10 for maximum inlet sizes for
endwall and side portals. You need not feed every row if utilizing
internal manifold feature.
If manifold installation does not include CULTEC’s side portal internal manifold,
proceed according to the engineer’s drawings for manifold pipe installation.

CULTEC Heavy Duty (HD) chambers must be used for any paved or traffic applications. CULTEC Heavy Duty chambers have a colored stripe permanently affixed along
the full length of the chamber. Chambers that do not have this stripe must not be used for paved or traffic applications.
All dimensions are nominal. Actual dimensions may vary on-site due to shipping and temperature.
Stone Backfill
Backfill using washed, crushed stone as specified in Table 3, page 13
and Table 4, page 14. To maintain row separation distance and prevent
chamber displacement, slowly distribute stone on top of chamber crown
so that stone builds between chamber rows as required.
10
For more information, contact CULTEC at (203) 775-4416 or visit www.cultec.com.
11. REQUIREMENTS
Stone Backfill (continued)
CULTEC recommends two methods of stone placement: excavator or stone conveyor boom.
Excavator-Placed Stone
Typically the most common method, excavator-placed stone is limited by
the reach of the arm. To accommodate this issue with larger beds, it is
common to prepare a bed by joining just a few chamber units at a time,
then placing the stone and fabric before installing the next few units.
The excavator is usually operated within the excavation area. The excavator
may work at grade level over recently placed chambers, provided cover-
age between the chambers and the excavator tracks meets the minimum
requirements as shown in Table 2, page 12 and Table 5, page 14.
Telescoping Conveyor Boom Placement
With booms as much as 120-140 feet (36.6 - 42.7 meters) long, telescop-
ing aggregate conveyors can greatly aid the process of stone placement.
With both stone-placement methods, ladling the stone carefully over the
chambers’ centers will secure them in place. Evenly distributing the stones
will help prevent chamber movement and maintain row separation.
Once secured, stone may be placed to surround the chambers and fill the
perimeter areas. System cover/backfill requirements will vary based on
CULTEC chamber model. Please refer to Table 5 on page 14 and engineer’s
drawings. Do not allow equipment to drive over the chambers unless the
minimum cover as shown in Table 5, page 14 is in place.
Repeat steps until all of the last chamber units are in place. Be certain to
use the Model E to end the line of chambers in place as specified by the
drawings.
If a manifold system is designed on the back end of the chamber bed, fol-
low manifold installation instructions as described previously.
Backfilling Requirements
• Place the stone over the entire bed area as described in previous section (See 2 in Figure 1 on
page 13). Cover the entire installation area with CULTEC No. 410 non-woven filter fabric, start-
ing from the perimeter and laying it atop the stone. The filter fabric must overlap at least 24
inches (610 mm) at the edges.
• Fill the first 12 inches (205 mm) (See 3 in Figure 1 on page 13) with enough material to meet the
requirements as shown in Table 3, page 13. Backfill over the top of the filter fabric (See 3 in Figure
1 on page 13) in lifts that do not exceed 6 inches (152 mm), and disperse the fill with a vehicle
that meets the maximum wheel loads or ground pressure limits as specified on specified in Tables
1 & 2 on page 12.
• Compact each lift of backfill as specified in the engineer’s drawings. CULTEC specifies compact-
ing to a minimum of 95% of the standard proctor density using a walk-behind or vibratory roller
with a gross vehicle weight of less than of 12,000 lbs (5,400 kg) and a maximum dynamic
force of 20,000 lbs. (9,000 kg).
• Backfill over the chamber bed (See 4 in Figure 1 on page 13) in 6-inch (152 mm)
maximum lifts until the specified grade is achieved. CULTEC’s cover requirements vary by
model. See Table 6, page 15 for minimum and maximum coverage. For pavement sub-base or
special fill requirements, see engineer’s drawings.
• Backfill height differential should never exceed 24 inches (610 mm) with adjacent chambers.
Minimum depth of cover of properly compacted material must be met before allowing vehicles
to drive over the bed. Avoid using large rocks and/or organic matter as backfill material. See
Table 3, page 13 for acceptable cover materials, or contact the design engineer for approved
fill types.
