Based on these phenomena,advice in conducting anti-fire conceptual design is put forward on both joints and steel frame.

The study of seismic concept design of multistory masonry buildings;

The complex structure system exceed the demand of code for structure design at many place,but these problems were solved preferably by seismic concept design,and the efficiency was proved by vast analysis.

In this paper,the importance of anti-seismic concept design and anti-seismic measure on fujian rural area building construction was discussed basing on the investigation of seismic disaster of jiujiang earthquake.

This paper demonstrates that the coupling effect on structure and ground should be considered thoroughly when involving with anti-seismic concept design.

Combined with present aseismic design code for buildings and engineering practice the main contents of seismic conceptual design of masonry-concrete building are introduced;at the same time corresponding assurance measures are proposed in order to fundamentally increase the earthquake resistance capacity of masonry-concrete building.

The importance of seismic conceptual design and the prevention of quasi - resonance and torsional damages of high - rise building under strong earthquake are ernphasized.

Some aseismic design concepts were provided.

This paper gives descriptions of seismic hazard of masonry buildings, seismic conception design, and anti—seismic measures, furthermore puts forward some detailed measures in strengthening the seismic ability of masonry buildings.
