1. Performance Limitations of Single Structural Residential Construction

Traditional premium residential buildings mostly adopt single construction systems including pure concrete structures, independent steel structures, and single lightweight metal frames. Each single structural mode has irreparable performance limitations, making it difficult to meet the comprehensive quality standards of modern premium homes that require safety, aesthetics, flexibility, and durability simultaneously.

Concrete masonry residential buildings are the most common traditional housing form with high rigidity and stable compression resistance. However, their fatal drawbacks restrict high-end residential quality improvement. Concrete structures have heavy self-weight, leading to high foundation bearing requirements and poor seismic toughness. Under earthquake disasters, rigid concrete walls are prone to brittle cracking and collapse, bringing potential safety hazards. Meanwhile, solid concrete walls limit spatial layout flexibility, unable to support large-span open indoor spaces and personalized architectural design. In addition, concrete buildings have poor thermal insulation performance, high operational energy consumption, no recyclable value, and generate massive construction waste during demolition, failing to meet green and low-carbon premium residential standards.

Independent pure steel structure residential buildings solve the seismic and spatial flexibility problems of concrete structures. High-strength steel main frames provide excellent bearing capacity and large-span expansion space. Nevertheless, single steel structures have obvious disadvantages in refined construction and detail control. Thick steel components lead to large self-weight and high transportation and assembly costs. The single structural form lacks refined partition framework support, resulting in single indoor layout and insufficient detail structural precision. Moreover, pure steel structures require complex auxiliary processing and repeated anti-corrosion maintenance in later stages, increasing the comprehensive operation cost of premium homes and affecting long-term residential value.

Single lightweight metal frame buildings feature low weight, high assembly precision, flexible splicing, and fast construction speed, which are suitable for rapid construction scenarios. However, limited by material thickness and structural design, independent metal frames have insufficient overall bearing capacity and poor extreme weather resistance. They cannot resist strong winds, heavy snow accumulation, and severe seismic impact, and are only applicable to low-rise and small-span temporary buildings. The insufficient structural stability makes single metal frames unable to meet the safety and durability standards of long-term inhabited premium residential buildings. In general, the unilateral advantages of single structural systems cannot cover the comprehensive demands of modern premium homes, urgently requiring innovative integrated structural construction technology to break through industry limitations.
