Modular coordination
Modular coordination is a concept where buildings and components are dimensioned and positioned based on basic modular units. This allows for dimensional compatibility and simplifies construction. The basic module is 100mm denoted as 1M. Multiples and fractions of the basic module can also be used. A modular reference system establishes grids to coordinate the placement and sizing of building elements and components. Structural elements like walls, floors and columns are dimensioned to fit within the modular grids, as are non-structural components and finishes. This standardization aims to reduce waste and improve construction efficiency.

IRJET- A Performance Study of (G+20) RCC Structure using Framed Bundled B...
This document presents a study on the performance of reinforced concrete (RC) structures with different arrangements of framed bundled braced tube systems under seismic loads. Four models of a G+20 RC building are analyzed using StaadPro software: a bare frame, and framed bundled braced tubes located at the periphery, internal columns, center, and corners. Parameters like base shear, story displacement, and story drift are compared. Results show that framed bundled braced tube systems improve seismic performance over bare frames, with peripheral and corner-located tubes performing best by increasing base shear and reducing displacements. This highlights the effectiveness of the tubular system for high-rise buildings subjected to lateral loads.
uni arc
The document proposes a design for UniArc Residences, a student residence building at Infrastructure University Kuala Lumpur using shipping containers. The 16-level building would house 990 rooms across 3 blocks using different sized containers. Structural analysis using STAAD.Pro shows the steel structure of columns, beams, and bolted connections can support the container loads. Shipping containers provide cost and construction benefits over traditional materials.
Designing for long spans 2
The document discusses long span and complex structures. It defines long span structures as having a span larger than 20m and being unable to be achieved by ordinary reinforced concrete structures. It then covers various types of materials used for long span structures and common structural forms such as reinforced concrete, precast concrete, structural steel, and portal frames. The document further categorizes long span structures into form active, vector active, section active, and surface active systems with examples provided. Notable overseas and Chinese examples of long span structures are highlighted such as stadiums, airports, and exhibition centers.

Steel structures
Steel structures involve structural steel members designed to carry loads and provide rigidity. Some famous steel structures include the Walt Disney Concert Hall, Tyne Bridge, and Howrah Bridge. Steel structures have advantages like high strength, ductility, elasticity, and ease of fabrication and erection. The Howrah Bridge is a steel cantilever bridge that connects Howrah and Kolkata. When built, it was the 3rd longest cantilever bridge in the world. It uses steel components like I-beams, rivets, and expansion joints and was constructed between 1936-1942.
CT Assignment Written Report
(1) The Petronas Twin Towers in Kuala Lumpur, Malaysia were the tallest buildings in the world from 1998 to 2004. They were designed by César Pelli and Associates and took 6 years to construct at a cost of US$1.6 billion. (2) The towers' structures are composed of reinforced concrete with a central core and perimeter columns connected by ring beams. High-strength concrete was used for the cores and columns to reduce wind response. (3) Industrialized building systems such as prefabricated steel beams, the preassembled skybridge, and prefabricated pinnacles helped speed construction and ensure quality despite the ambitious schedule.
