What Are the Common Types of Building Structures?

 When buying or renovating a home, you often hear terms like "brick-concrete structure" or "frame structure." But what exactly are these? In essence, they represent the different "skeletons" of a building—elements that directly impact both residential safety and the potential for spatial modification.

1. Brick-Concrete Structure

This type of structure is quite common in everyday life. It utilizes brick walls as the primary "bones," reinforced by poured concrete beams and columns—much like building something piece by piece using building blocks. Frequently employed in the construction of low-rise or multi-story residential buildings, a brick-concrete structure—as the name implies—consists of brick walls combined with reinforced concrete floor slabs. The construction process is relatively fast and convenient for low-rise housing; indeed, many older residential complexes feature this structural design. However, its seismic resistance is relatively poor, which is why buildings of this type typically do not exceed six stories in height.

2. Frame Structure

This approach involves first erecting a "framework" of steel and concrete (comprising beams and columns), and then using lightweight materials to construct walls that serve as partitions. It is akin to assembling a LEGO frame, where the interior panels can be freely rearranged. This structure is commonly found in mid-to-high-rise buildings ranging from 10 to 15 stories. Its greatest advantage lies in spatial flexibility: during renovations, non-load-bearing walls can be removed to alter the floor plan. Furthermore, it offers superior seismic resistance compared to brick-concrete structures, though its sound insulation is slightly inferior, and construction costs are higher.

3. Shear Wall Structure

Worried about high-rise buildings swaying? Shear walls are the ultimate "anti-sway solution." This design integrates the walls directly into the structural "skeleton," casting them as solid, reinforced concrete panels. These walls serve a dual purpose: bearing vertical loads while simultaneously resisting horizontal forces—effectively equipping the building with a protective "shield." This structure is predominantly used in high-rise residential towers exceeding 30 stories. Its advantages include exceptional seismic resistance and structural stability; however, its primary drawback is that the walls are almost entirely non-removable, thereby severely limiting options for spatial modification.

4. Steel Structure

This method utilizes steel beams and columns to construct the building—much like assembling a giant set of steel building blocks—resulting in rapid construction times and high structural strength. In China, this type of structure is primarily applied in large-scale projects such as sports stadiums, bridges, and industrial plants; Beijing's "Bird's Nest" stadium stands as a quintessential example of steel-structure architecture. However, the disadvantages include high construction costs and a susceptibility to rust, which necessitates regular maintenance; consequently, this structural type is rarely used in standard residential housing.

What is the difference between a girder, rafter, and purlin in steel structures?

图片
  In steel structures , girders, rafters, and purlins are all structural components that play different roles in supporting the building's load and providing stability. Here's a breakdown of each: 1. Girder:     - A girder is a large horizontal beam that supports other beams or loads across an open space, such as a roof or floor.     - Girders are typically placed perpendicular to the beams they support and are designed to carry heavy loads over long spans.     - In steel construction, girders are often used in building frames and bridges to distribute loads from the beams to the columns or supports. 2. Rafter:     - A rafter is a sloped structural member that supports the roof covering and transfers its load to the walls or other supporting elements.     - Rafters are commonly used in roof framing to provide structural support and to create the pitched shape of the roof.     - In steel constr...

ROOFING CONSTRUCTION TECHNOLOGY OF SADDLE-SHAPED OVERHANGING STEEL STRUCTURE RETICULATED SHELL SKIRT BUILDING OF HANGZHOU GATE SUPER HIGH-RISE BUILDING

  Hangzhou Century Center, which is the tallest building under construction in Hangzhou and the tallest twin tower building in the Hangzhou Bay area, is known as the gate of Hangzhou. The wings of the two towers of Hangzhou Gate, together with the surrounding Olympic Sports Center, natatorium, International Expo Center, as well as the civic center, international Convention center, and grand Theater on the other side of the Qian River, form a "seven-star bright" urban picture. The Gate of Hangzhou is like a cloud floating in the seven stars, with a strong sense of design and visual impact.   The main body of Hangzhou Gate is composed of symmetrical 63-story east and west towers, with a building height of 302.6m and a total construction area of about 532,500 square meters. The east and west towers are connected by steel arch Bridges on the 1st to 6th floors above ground. The maximum span of the bridge is 85m at the north and south ends, the minimum span is 55m in the middle...

The Development of the Structural Form of Gas Station Canopy

Since Portland cement was invented in 1824, after half a century of research and development, it was not until the middle of the 19th century that concrete structures began to be applied. Because the quality of concrete and cement was relatively poor at that time, and the theory of design technology had not yet started, the development was relatively slow. At the end of the 19th century and the beginning of the 20th century, China began to build buildings with reinforced concrete structures, such as Shamian in Guangzhou and The Bund in Shanghai. However, when our country was first established, the steel output was very low, only 1.35 million tons per year. At that time, the construction of steel structures in China could only rely on the economic and technical assistance of the Soviet Union. It can be seen that the appearance of reinforced concrete structures in China was earlier than steel structures. The structure of the gas station canopy in China was a reinforced concrete frame s...
